First, I’m a long time trackball guy due to rsi from my job going back to the MS intellimouse trackball explorer in the early 2000’s. Wore a few of those out. I dislike the thumb-ball varieties that are much more common as I prefer the fingertip precision more. Tried the square trackball (Kensington expert) for many years and it was the best option until the Elecom huge. I love the feel (i have large hands) and have been using this every day since i bought it in 2020. Still holds up!! Wearing out the padding a little, but still mechanically excellent. The button setup is a little wonky (been using mouse assistant 5, but upgrading to 6 later today), but once you get it sorted, it just works and I very much enjoy it. I do wish it had a battery charge indicator as it just stops working when the battery dies. Might upgrade to the huge plus….
If you have large hands and prefer fingertip trackballs, this is what you want.

It's not Large, it's HUGE
The Short & Sweet: I bought this to replace a nearly 20-year-old Kensington Expert trackball mouse which was showing signs of failing. Looked over (and rejected) Kensington's current offerings, choosing to try a different configuration. Looked at a few Logitech models, but the most interesting model was incompatible with my desktop setup (older Mac Pro running High Sierra – yes, I have my reasons, being a cheapskate not being one of them). Came across this model, which I'd never heard of, from a brand I'd never heard of, but it seems the HUGE has been in production for the better part of a decade, so I thought "how bad can it be?" Short answer: not bad at all: love the ergonomics of the thing, actually easier on my hand/wrist than the Kensington, and wireless connectivity is solid and smooth. Makes me wish I'd made the switch sooner! Recommended.

Ergonomics are not good (for me)
I decided to give the Elecom Huge a try as my current Nulea trackball was having some minor issues with the scroll wheel as well as catching/friction on the trackball against the roller bearings, despite thoroughly cleaning and relubricating. My initial impressions of the Huge were good; the larger trackball felt more precise, and the ball tracking itself was very smooth. It didn't take long for the smoothness to wear off and for me to start noticing some ergonomic issues.
First, I'm seriously disappointed that within days of use it feels like the rollers already need some cleaning and lubrication. I haven't given that a serious attempt just yet, but I would like to point out that I've had trackballs costing half the price as this one perform better in that aspect. There's also some other disappointments such as the battery not being rechargeable, no option for a wired mode, and 2.4G performance being a bit lacking when the dongle is not optimally placed. As far as I can tell, 2.4G is the ONLY wireless mode (no bluetooth), and while I generally prefer it for its responsiveness I'm experiencing signal issues that I never had with other wireless mice at this workstation.
Next, the ergonomics are, quite frankly, horrible, and part of the reason I wanted to try this mouse was because I wasn't 100% satisfied with the Nulea's ergonomics. The Elecom causes me wrist pain in such a shorter period of time, and I can almost entirely boil it down to the way the wrist rest flares out towards the bottom. This effectively increases the height of the rest and puts more pressure/mechanical strain on your wrist and palm. By contrast, something like the Nuela mitigates that, and also is appropriately contoured to help promote a more neutral wrist position. I found that propping up the front of the Huge does help a little in my case (you can see a mint tin as a temporary solution in my picture).
Finally, I will give Elecom a point for their lightweight customization software, and generally the click feel is good and actuation pressure is appropriate. The scroll wheel is alright, but I don't like the amount of force required to scroll-click and the added up-down movement (or left-right, technically) doesn't feel great and has limited usefulness in modern software. For example, in most programs it is excruciatingly slow, despite being set to the highest speed via the configurator.
Overall, ergonomics aside, since that tends to be very individual, the Elecom Huge fails to differentiate itself from competing trackball mice in terms of performance, though the larger trackball and integrated wrist rest are unique. Connectivity and charging options are lacking, and the Huge struggles to keep up with even generic brand trackballs that cost half the price. I really, really, want to like this mouse, and felt that 3 stars may have been too harsh, so I'm rating it 4. Truly, it's more like a 3.5 than a solid 4. I would still recommend giving it a try, but I don't believe that it's going to be for everyone.

Genial, super bien para trabajar y editar o diseño gráfico
Excelente y funcional. Súper comodo para editar y para cualquier otro programa o aplicación. tiene todo.
Si hay algo que tendría que mejorar es el material. de mejor calidad, aunque por precio esta bien, pero pagaría un poco mas porque tuviera mejor material. botones mas pequeños y bien ajustados. sin embargo le pongo cinco estrellas porque el mouse es de lo mejor que he probado. incluso mas que los logitec trackball. lo compraría nuevamente. y mejor si tuviera mejores materiales mucho mejor. pagaría el doble con tal de sentir botones mas ajustados y materiales mas solidos. sin embargo por el precio esta super bien.

Not a Perfect fit, but far better than most
I like the overall size, build quality seems decent, I don't like how sensitive the scroll wheel is though or it's placement, it would be better if it were moved up a bit and given a bit more tension on the bearing so that it doesn't roll with an accidental bump, the right click button is also a bit too narrow, when I go to click it I generally hit the function button next to it as well (good thing I haven't assigned it to do anything), but overall it is a big improvement over most mice on the market right now, it's just taking some getting used to...
Update: Dec 19 2025, Still works just fine, hasn't broken at all despite being dropped many times, Still feels a bit small for my hands, but I still haven't seen anything else on the market that comes as close as it does to fitting.

Left click is too low.
WHY I BOUGHT THIS: I need a 2nd keyboard and mouse combination at my desk for work. I'm short on space so a trackball of some sort will work better than a mouse. Buttons-a-plenty.
PROS: The trackball is silky smooth. The left and right click buttons have a satisfying, quality crispness to them that don't sound hollow. The scroll wheel has a tactility that makes thumb scrolling a breeze.
The combination of buttons and software provides a wealth of customization.
CON: Location of the Left Click requires extending and/or curving your thumb down in an unnatural way.
I wanted this product to work as I saw the wealth of possibilities with the number buttons on it. When I got it on my desk and noticed the trackball was as good as any Kensington or Logitech I was excited. I replaced my Logitech MX Vertical and figured I'd give myself a couple of days to really get a feel for this mouse so I could potentially recommend it to people who didn't want to cough up $100 for the MX Vertical. Immediately I noticed the joint that rotates my thumb was coming into play to left click. Right-Click looks like its in a strange place but I found it natural to reach for. I figured I was just used to a handshake mouse and NO movement so I went on to work. I left this mouse in place until lunchtime the next day when I could no longer stand extending my thumb down from where it naturally is when your middle two fingers are on the trackball. I even tried with my pinky top dead center on the trackball and still had to extend my thumb or reposition my hand. I have an ELECOM thumb mouse that's less stress on my thumb than this was. You COULD reprogram the Forward button to be left click in the software, yes. The Forward button is a silent soft click though and that sweet sweet crispy left click button would be wasted. PLEASE ELECOM either swap Forward/Back buttons position with the left click OR mold the plastic so that the thumb rests lightly on Left-Click so this thing will be the ergo dream that I know it can be!!! I had to return this item as all the reaching didn't work for me but I look forward to the day when I will be able to purchase something other than Kensington or Logitech.

It doesn’t work..
I’m pretty sure I was sent a used product. As soon as I cut the top seal off with my xacto knife and pulled out the mouse.. I noticed it was already dusty at the bottom.. like it was being dragged on a dirty desk. I also took out the trackball and saw it was dusty inside as well.. I overlooked it and said “well if it works.. that’s fine. I won’t return it”. I tried connecting it to my work computer, currently running windows 11, and it didn’t work. Mouse did not come with English instructions and again, I was ok with that. It says that when it’s connected it will prompt a driver download.. didn’t do that.. again that’s ok, not the first time I’ve dealt with something like that. So I searched for a driver.. installed it… and still .. not working. I flipped the switch to L and H at the bottom.. I see the red light turn on inside the mouse… switched batteries… changed usb connection port.. restarted my computer… nothing.. now I’m thinking someone returned this product for the same reason and it was shipped to me as a “new” product. After inspecting the box, I noticed the bottom flap was forcibly opened.. I don’t like to open my boxes like that, I prefer doing a precise cut if possible incase I plan on keeping the box.
The mouse looks great, feels great, and I was deeply excited to use it.. but it just doesn’t work. I’ll be returning it, I’m hoping I can get a new replacement because this def looks like a top contender to replace my current mouse.

GREAT!… with mods
I tried several different trackball mice before finally landing on this one. I tried thumb scrollers and a couple different finger tip scrollers likes the huge. The main thing that drew me to the HUGE was not the giant ball, which is nice, but it was the tons of customizable buttons. The buttons have completely transformed my workflow. The software for programming the buttons is great, once you figure out how to change it from Japanese.
There were a few mods I had to do to make this the best trackball for me.
First and foremost: the bearings. This is an essential mod. The bearings this mouse comes with are hot garbage. The “stiction” is abysmal and makes this mouse feel like a budge mouse half the price. I highly recommend steel bearings or any comparable option.
The second mod I did was 3D print a wedge to go under the mouse to hold it a 10 degree angle off the desk. I found that keeping the mouse flat on the desk caused fatigue in my wrist. You can find the print files online. In the same vein as this, I also printed a palm wrest (pictured). When using this mouse your hand hovers over it which can also cause fatigue.
The third and final mod was replacing the clicky switches with silent switches. Half the buttons on this mouse are loud, and half are silent. Weird, right? After using the Logitech MX Master 3S and experiencing silent clicks, I couldn’t go back. The left click, right click, and FN3 switch are all standard OMRON switches and can replaced with any of your choice. Now all the buttons are silent (as they should be lol).
After doing all of these mods, I can confidentially say this mouse is the best investment I’ve made in my productivity and I couldn’t recommend it more!

My third review - Trackball users READ THIS...
I just purchased my third one of these and have finally learned how to make it as smooth as any trackball in existence.
I wrote two previous reviews recommending changing the three bearings that support the ball because I read a review about doing that and tried it. (It worked okay, but was a lot of work and these trackballs are very difficult to take apart and reassemble.) But now after years of experimenting and reading other reviews, I've learned that it's easier than all that.
Simply take the ball out, put in two O-rings and two steel bearings in the little cup and you're done. Takes all of about 60 seconds to do. Then, rub the ball on your forehead or next to your nose and put some natural skin oil on it and snap it back into the housing.
Now, enjoy the smoothest zero-stiction trackball action in the milky way.
The picture of the cup shows one O-ring and bearing installed and also one O-ring without the bearing. I did that to show the process - (remember to put in two bearings not just one like in the picture.) Tweezers or fingernails is all it takes.
Also in the pictures, my baggie of bearings are 3mm. I've found them to be just a tad too small, so go with the 3.5mm ones that i posted in the link above. (I have to back the screws below the O-rings out about a half turn to raise the bearings up using my 3mm bearings, but with 3.5mm bearings that won't be necessary I think.)
The only con is that when you invert your trackball, or bang it too hard, the bearings fall out and get forever lost. :(
So, buy a bunch of bearings (the O-rings tend to stay put).
I was not offered nor paid anything for typing this. Simply sharing with fellow trackball enthusiasts.
Linux users: It works fine with LMDE and Mint (I've tried both). Get 'Input Remapper' from the repository, and you can configure each and every button to do exactly what you want. No need for the OEM drivers that Windows makes you use. :)

LOVE!!!
I have the Logitech trackball at home and needed one for work. I scored this one and I love it. It’s perfect for me!!! It’s taking me a little longer to get used to it because it’s a bit different from the Logitech trackball mouse. The set up was simple. I inserted the batteries and the receiver and it worked immediately. I just have to get used to its functions. I would gift this and purchase again. HAPPY!!!

Ergonomics for Large Hand
My hand span is 8.5 inches, so probably average or better. Over 23 years, I've worn out four Logitech TRB-22's which can no longer be fixed.
I bought both an ELECOM Deft Pro and a HUGE for comparison. After using both ELECOM trackballs for over a week, I've concluded that the HUGE is more ergonomically pleasing due to the large wrist platform and the 44mm ball; conversely, the Deft is much smaller and does not effectively support the wrist.
Moreover, it's much easier to reposition the HUGE on the desk, but when moving the Deft, there is no good way to grab the unit without making a left click... a minor annoyance, not critical.
Of course, neither is as good as the Logitech, but unlike the Logitech, the ELECOM ruby ball bearings can be upgraded to ceramic or better.

PRETTY GOOD FOR CAD DESIGNING
I make a living creating structural designs for retail display packaging. My right hand (mouse hand) was going numb/cold several times a day due to the normal mouse I used so I decided to give trackball-style mice a chance. I settled on this Elecom Huge because of the size, layout, and features. It has been a couple days and I am pleased with it so far. I have not had a numb/cold hand yet and I don't need to crack my knuckles or wrist even after several hours of continuous use.
Notes:
* The trackball is truly large and sensitive making it easier to use with precision than I expected.
* All of the buttons are programmable including the multi-direction scroll wheel which is incredibly helpful when doing CAD design.
* The Elecom web app for button programming is not as intuitive as other brands, but after some experimenting I got all my shortcuts programmed. If you've never programmed mouse buttons before you might want to check YouTube when you get stuck.
* I would like it to have a higher pixel sensitivity (1500 is max) but it gets the job done well enough when combined with the zoom feature.
* I am able to run it and my old mouse at the same time and find myself grabbing the old mouse subconsciously when doing non-CAD work. Still, the ability to have that option is very handy.
* Most people consider me to be a substantial person at 6' 5" and 255 lbs. My hand fits very comfortably on the Elecom Huge and I imagine people with smaller (normal) hands would find it even more comfortable. The scroll wheel is mounted a bit too far rearward for my thumb to use w/o adjusting my hand a little.
All in all, this was a great purchase. 5 stars for sure.

Microsoft Trackball Optical User Comes Clean, Still Prefers Wired
Generally speaking: I long miss my (several) Microsoft Trackball Opticals. I've been using various iterations of the Logi thumb operated trackballs. All around the Logis have been good to me and are especially great for travel given their compact size. I've been looking for a trackball with a full sized palm rest and decided to give the ELECOM a try even though it's not a thumb operated ball.
The overall form factor is fantastic (sorry lefties, best wishes)! I was hesitant to make the switch from thumb to fore/middle finger. At first, yes, it's an awkward change going from thumb to index. The first suggestion I can provide is to use the different trackball button assignments to match the button presses you are used to. Even if this means assigning the same function to multiple buttons at the start. Plenty of time in the future to set distinct button assignments after getting used to the new layout.
Most importantly, have your thumb operated trackball at the ready! For long time trackball users it won't take long to transition to the new layout, but it's important to slowly introduce the new layout. I used the ELECOM as much as I could but still switched back to my Logi if I needed to get something done ASAP or just got frustrated with the change. Building muscle-memory for a new trackball layout took way less time than going from a mouse. Plus I've used the Logis for so many years switching back to the thumb design when needed hasn't been an issue.
Specific to the ELECOM HUGE Trackball Wireless model: Absolutely a great trackball for someone looking for a large form factor, regardless if you are currently using a thumb operated ball design! Just be sure to pick up a pack of lithium AA batteries for this ELECOM model! I've been spoiled by the wireless Logi's running on a single AA for over a month and even the Logi's ability to take a "used" AA to scrape by is impressive.
I haven't done a deep investigation as to what is the biggest drain on the ELECOM battery life. If I had to make an educated guess the Logi is going into a deeper standby/sleep mode than the ELECOM. Update rate could also be playing a part, but I've been using the lowest (500) DPI ball tracking refresh rate. I get it if ELECOM is sacrificing performance over battery life by choice.
ELECOM REPS: What I don't get, and this is my only real gripe, is the robustness of the off/low/high power switch that is exposed on the bottom. Sure, it's in a handy spot to turn it off and save battery life. But turning it off all the time to save battery wares out the switch. Trying to keep it in low power mode eventually becomes more of a pain than just using high. It's a small item with a large impact.
tl;dr This trackball is also available in a wired version. For home/office the wired version has been flawless! It's a trackball after all – it's not like dragging a wired mouse around. Plus I still have the wireless model for use on business trips.

Great replacement for the Logitech Trackball
I have been using the logitech trackman trackball for over 20 years. And if you are like me, you know that every 2 years or so, you have to replace it. But they discontinued them and the secondary market is selling them for over $100, which is absurd.
So I set out trying to find replacements. Tried four different ones and ended up landing on “Huge”.
It took me about 2-3 days to get used to the change in feel. And about a week to configure the buttons the way that made sense for me based on my usage.
Have been using it now for about 3 months and even bought 4 (work, home, travel and 2 spares).
One thing that is great about these is the price. For the cost of 1 track man you get 2 of these. And so far, no issues with them.
You still need to take the ball out and clean the heads, but that should not be a shocker to anyone who has used track balls before.
If this is your first trackball, you are going to have a steep learning curve. It will not feel natural, but that is normal when making the switch from a “mouse” to a TB.
For everyone else, get it, try it out. It won’t break the bank.

BIG HANDS this is a must have
I'm 6'5" so yes I have big hands. For years I used a Microsoft Trackball Explorer even after one of the buttons stopped working. After a recent upgrade to an Apple Studio, I knew I needed full functionality of my mouse. After trying a few other standard-sized mice I saw the HUGE pop-up in suggestions.
If you have big hands this is an absolute must-have. It is so comfortable right out of the box. The ball glides smoothly with precision, buttons have a light easy touch. With all the button options you can easily set up several profiles to be used with different applications. Once I downloaded the mouse utility and restarted my computer setup was super easy. With so many button options to customize to your preferences this by far is the most versatile mouse I have ever used. Additionally, even if you don't have monster paws you will find the HUGE mouse to be very comfortable to use.
PROs: it's huge, easy to program, wireless, very comfortable, and has lots of buttons.
CONs: No Bluetooth, No USB charging (requires 2 AA batteries, you will receive 2 with your purchase) only comes with a USB transmitter and not a USB-C. (my Mac STUDIO has only 2 USB slots but 6 USB-C slots)

First time using a trackball
For my first time using a trackball mouse this mouse ok, just ok. You can change the all the buttons and the speed for the pointer. the problem is the size I might have medium sized hands but the benefits are for small hand people because if I laid my palm on the mouse's hump or hill my fingers are too far for me to reach so I needed to place my palm on the edge of the soft pad to get everything lined up. The mouse takes a little getting used to but its not that big a deal.

The worst
I do a lot of video and photo editing and saw this and read all the reviews. Positive reviews at that. So I ordered this and it came on time. This thing is huge. Reading the reviews there is a small learning curve so I updated all that I could and paired it on my Mac. It started smoothly and within seconds it became totally inconsistent. I made sure the adapter was facing the mouse so that there would not be an issues and still it was inconsistent. It is not smooth and the mouse stutters throughout the screen. I tried to change settings and so that was a bust also. It could have been great to get it to work but I spent all night trying everything to get it to work. I attached a small video clip to show the issue. The first movement is the mouse pad on my computer and then you will see where the mouse stops and then continues which where I started to use the purchased mouse. It works for a couple of seconds then starts to stutter again. I tried to press the button to stop the screen recording and couldn't even get close to it. I stopped and use the mouse pad on the computer to stop it. May be a gamble for most and maybe I got a bad one according to all the positive reviews posted so who knows. Good luck if you purchase this.
Update....still haven't been able to get this working. It is not a $70 paperweight... it holds the paper down really well. You can always play with the ball and buttons, which can be used as a stress gadget. Definitely try another mouse or take the chance and try this one. Good luck and have a good day.

It's "Huge" and It Worked Right Out of the Difficult-to-Read Box
Look, we get it. Pretty much all of our electronics, regardless of brand, comes from China. However, in this case, even the packaging is in Chinese despite the target market here in the U.S. If I had seen this on the shelf at my local big box store, the language barrier would have prevented me from buying it, and I'm sure others feel the same. Yes, when you open the package there's a tiny insert with English instructions in tiny font, but most people won't get that far. At least the labels and switches are labeled in English.
This trackball is as advertised, e.g., "huge," and shaped for right-hand users. Overall I'm happy with it, although the left click button requires that I curve my thumb awkwardly around the tilt-wheel to trigger it, and the right click button doesn't feel like it's quite in the right place. These quibbles may be because I'm switching over from a symmetrical shaped device and I'm still getting used to it, so I'm not going to grade this too harshly.
The good news is that it worked correctly right out of the box on my Windows 10 Dell tower. The ball moves smoothly, the wheel (which I lacked on my previous device) is convenient, and the speed setting was easy to adjust with a three-position switch. (For me, "low" was still plenty fast.) I haven't installed the driver software yet, but I plan to do so and program the three function keys when I get back from Buttonwillow Raceway next week.
This trackball has more features than many and the price is somewhat higher as a result. If you're looking for cheap and basic, look elsewhere. For me, I think I'm satisfied and am probably going to stick with it.

Don't be afraid of this mouse!!!
ELECOM 2.4GHz Wireless Finger-operated Large size Trackball Mouse 8-Button Function with Smooth Tracking, Precision Optical Gaming Sensor (M-HT1DRBK)
Don't be afraid of this mouse!! I was debating for days whether or not I would get it. The learning curve is not that bad. Took me about 3 weeks to get used to it but was comfortable from the start.
First Trackball Mouse I have ever used. I have been using this mouse for the past two years. I thought I write this review because I have seen improvement with my right hand wrist pains. This review is based on that perspective. Pics will show how it looks with a little wear and tear. It holds up very well. With a little cleaning it would look like new.
After years of computers I needed to give my wrist a rest or at least change it up. As a web developer for many years now I needed a change. It has many programmable buttons. Every button can be mapped using the included software.
Very sturdy! The mouse balls come out. Definitely take pressure off my mouse wrist.
Was a little skeptical about the two finger controls of the mouse instead of the thumb trackball. This actually works better for me. I like it better for my wrist. It elevates sooooo much work that a traditional mouse would on my wrists. It has some weight which is a good thing since this is a trackball mouse. Feels sturdy.
Easy to clean. Removable trackball to clean inside the trac and ball. If your paying less $80 it will be worth it.
The real star is the many programmable buttons it has. Every single button can be remapped to either windows functions or keystrokes. Buttons feel comfortable along with the padded wrist pad attached to the mouse. Easy to program with the software. You can program Macros with the software alongside button assignments.
Gaming on it can be done. It depends on what game and playstyle. I tried it for a game or two but
The feel of this massive mouse is great. I don’t have large hands nor small ones. So this mouse feels great in my hand. It will feel great with larger or smaller hands.

Rolling is not smooth
I've only had this a couple of days so I can't really give a full opinion on it. What I can say is that the rolling is pretty crappy for small\precise movements. I've since watched several videos on youtube and most of them have all recommended buying and swapping out the synthetic bearings that come with it for ceramic bearings. They say that doing so it like using a completely different mouse.
I just ordered the bearings but the fact that I have to pay 6 more dollars, and then completely take the mouse apart to replace something to make it useable is not really a good start.
I added a video and you can see how the friction makes the pointer jump when you try to move it in short\small distances.
Other than that, I like the mouse and want to keep it

A well designed, comfortable, accurate trackball
I really enjoy using this trackball because it is so comfortable and easy to use. After suffering a wrist injury, surgery left my wrist function at about 60% with pain under certain instances. Using a regular computer mouse is one of those instances and the keyboard mouse on laptops is definitely painful. This trackball is designed well ergonomically. I can lay my hand on it and it supports my wrist as well. All the buttons, wheels and ball are within perfect reach of my fingers so I never have to shift my hand or stretch my fingers to reach them. I am very pleased with the ball accuracy too. The pointer goes precisely where I want it to go, no lags, flickering or loss of control. The settings adjustments allow the trackball to be tailored to my personal use. I did install the app which is a companion to the track ball. The app allows for more customization including asssigning functions to buttons.
The only gripe I have is that the on off switch is located on the bottom of the trackball. You have to pick the unit up, flip it over, and use your thumbnail to turn it on and off. They could put the switch somewhere on the top side of the trackball as there is ample room for it without interfering with anything else. This issue is minor however and I won't remove any rating starts for it.
All in all, this is a well designed, sturdy, well thought out trackball that I recommend you try out.

Best available trackball
I've been searching a long time to replace my previous trackball, which is no longer in production. This is 90% there, which is to say WAAAAYYY better than anything else I've tried. It is large though not "Huge," but about the size of a gaming 10-key. My hand which is a size 9 fits it easily, buttons are in mostly comfortable locations, and the wrist pad is great. I tend to roll with my middle-finger, but can easily use my Index or Ring fingers if I want.
As for the other 10%, I do wish the ball was actually a bit bigger or the whole body angled a bit more, but that is just my preference. The other improvement I would like is for the left-click button to be under the thumb rather than on the side--so it would be more like hitting the space-bar than pinching a pencil.
Pros:
Lots of buttons
Button Chord support -- for what amounts to even more buttons
Scroll wheel
wireless
Comfort
Con:
Main-button on side

No more running off the mouse pad
I bought this because I was sick and tired of running off the mouse pad. I would be watching the screen and the mouse would get stuck. I'd have to pick it up and reposition it in the center of the mouse pad. No more running off the mouse pad.
As you can see in the pictures, there is plenty of desk space using this and no more having to make room for your hand to move around on a cluttered desk. I have distant pictures that show the size in comparison to the keyboard and that is a 32" Samsung TV as the monitor.
The other pictures are two top pictures, a side picture, and measured pictures. Looking at the normal view top picture straight down at it (as if you were going to use it) there are two keys (R and Fn3) to the right of the trackball. The (R) key is the right click and the (Fn3) is a programmable key. Then there is the trackball itself (you can see how big that trackball is in the measured picture). On the left of the track ball there are two small keys (Fn1 and Fn2) which are both programmable keys. The other top picture (reversed position) is just a different angle.
Looking at the side view picture you can see there are two arrow keys (below the Fn1 and Fn2 keys). They are used for web browser page forward and page back. Below the arrow keys is the track or scroll wheel. Below the track or scroll wheel is the Left click button. The little slide button on top of the thumb rest is the pointer speed selector switch.
On the bottom of the Trackball is the Power button and the (L and H) mode for the high speed mode or low power mode. It does say that the tracking performance of faster ball movement becomes better, but the battery life gets shorter.
In the measured pictures you can see the size. The track ball appears to be over 2" in total size across. I guess that's why it's called "HUGE." The total length is about 7" and the width is 4 1/2" (+/-). My desk is about 43 1/4 x 19 1/2. As I sit here writing this review, I snapped a picture of the full view of the desk. It is a big as you can tell, but to me it is worth it. No more wishing your entire desk was a mouse pad.
On the customization, if your working on something personal and someone walks in the office, with one click of the (Fn1) button I minimize my screen. No more racing to the top corner of the screen trying to shrink it down. If you have two screen like I do, then the pointer goes to the other screen. Now your looking for the pointer and have to hire a search party just to find it. Seriously though, it is pretty awesome to minimize the screen with one click.
All in all I like it. I cannot review it longevity because I just got it. This is more or less a mini tutorial and first impression review. I like the first impression I received from them.

So thankful this thing exists, wonderful device
This may be premature as I've only worked with it a day, but I love this damn thing. I used to use a Logitech Marble FX, which was PS2, and went through insane measures to get it to work on a modern machine. I gave up and never thought I'd fine something I liked using again. This popped up and I was very interested but skeptical. I'm on a Macbook now, which made me even more so.
Likes: the software is easy to find and download, quick install, asks for a reboot but ok, allows very easy customization for any random thing I try to set up, and just works solidly and well. I haven't measured them, but the trackball feels nearly the size of the cue ball-sized one from my beloved Marble FX, and it's smooth and has buttons just just easily change the pointer speed. And they're set at speeds that really seem to correspond to what I consider "low", "medium" and "high", unlike "fast", "faster" and "lunatic", which is nice.
No dislikes as of yet. I did make a slight 15 degree wedge to place it on so my hand is more vertical since I'm paranoid about getting carpal tunnel, but that's a real easy fix. It feels perfectly fine just sitting flat on my desk. Recommend 100%.

As an MS Trackball Explorer user since The Win98/PS2 days, this is an excellent "replacement"
Quick Summary: MSTE users who don't have an MSTE - get this mouse as it's the closest "replacement" to date. Obviously, if one wants a mouse like the MSTE, then get an MSTE. But even a used MSTE costs a bit and you have to be careful of the cord. If one wants something Less Expensive that closely resembles the MSTE and is also cordless, then this is the best mouse on the scene since the MSTE itself.
Update2: Trying to add some slightly better pictures and others that show the MS Trackball Explorer, Logitech Cordless Optical Trackmall, and the smaller Elecom "DEFT" trackball mouse. But some pictures are not loading to the site. Sorry. :(
Update1: IMPORTANT NOTE: Waaay down in the comments (the oldest one at the "bottom" should be a link to the Elecom software download page and the English PDF manual. As this mouse is "very new" you *DO* need a more recent Elecom proprietary software to recognize this mouse if you wish to use it's three proprietary function buttons (F1-F3).
Long Winded Review
===============
In August I was about to order a second of the smaller Elecom M-DT2DRBKs when I stumbled over this new **larger** "HUGE" mouse and figured it was worth a try. The M-HT1DRBK just arrived and after giving it a ten minute test spin I just ordered two more. No clue if it will take "1-2 months" for the next batch to arrive, or if the price will drop from $85.99, but would say it is certainly worth the investment. FYI: It actually does say "HUGE" on the mouse itself. :)
Comparisons to the MSTE (MS Trackball Explorer)
======================================
1) It has a nice large "red ball" like a certain MSTE we all know and love. In fact, the Elecom ball is slightly BIGGER than the MS one. There were many reviews about the smaller Elecom mouse's "grey ball" having issues, and several people purchased a "blue" M570 ball to swap with the "grey" one. From my quick tryout of this new mouse with it's "red ball", would say that the quality looks to be significantly better than that of the smaller mouse's "grey" one. An excellent improvement.
2) This mouse is *MUCH LARGER* than the smaller "grey ball" M-DT2DRBK. Excellent for people with "larger" (aka normal sized) hands.
3) It is a bit wider than the MSTE, and Elecom moved one of the three proprietary "Function Buttons" to the right side of the ball. If you use their proprietary software, this would give you "two buttons to the right of the ball" just like the MSTE.
4) MOST IMPORTANT OF ALL. This mouse has a PALM REST. As this seems to be an alien concept to most mouse manufacturers I will state it again - this mouse actually has a place for the palm of one's hand to "rest" while using the mouse, so for the first time since the MSTE, there is actually a trackball that not only fit's one's hand, it is actually COMFORTABLE. Plus it doesn't have teeny tiny thumb-killing buttons like a certain L*git*ch Trackman. Wish I could show a decent side-view of the palm rest, but this can also be seen with via the pics on Elecom's web site.
5) ??? I would assume that being a wireless device, there may be an occasional "lag" in response times, but cannot say for certain. However there does appear to be a wired version of this mouse as well. It's part number (August 2017) is M-HT1URBK.
Usage
=====
Bulk of this review was written after only ten minutes of mouse use, so haven't had the time to give it an extended run, but observations so far are positive. "Weeks later" - Still great. Haven't tried the Elecom software yet myself (not using the F1-F3 buttons).
- Seems to respond MUCH better than the smaller Elecom version (blue or grey ball).
- Range seems to be about the same as the smaller one. About nine feet out it gets tricky and Line of Sight is critical.
- The "left" button isn't as "tall" as the MSTE's, so my clumsy thumb is hitting the wheel, but this should be a minor issue.
- ??? I read elsewhere that the "left" and "right" mouse buttons are "better quality" than the other buttons, that one should be able to tell the difference, that they should have made *all" the buttons "better quality", etc. Haven't noticed any difference between buttons yet. Too busy enjoying having a wireless mouse that actually fits the shape of my hand for a change.
Customization - aka The Buttons
========================
So far as remapping buttons, "drivers", and support for various operating systems... Would assume this mouse works as a basic mouse in anything from XP up to Win10. You've got your Left, Right, Forward, Back and Wheel Buttons, plus the three Extra Proprietary Function Buttons F1-F3. Remapping the eight buttons and basic customization is where it gets interesting. Would assume one needs at least version 5.1.0 of Elecom's proprietary software to use/control all eight buttons. For now I am sticking with X-Mouse Button Control which allows configuration of everything except the three extra Function Buttons. Both programs allow for the use of multiple profiles for easy customization across different applications. Elecom's software (and English PDF manual) is available from their website. I will try adding possible links as a "comment" later as this review is too long as it is.
Odd Future Issue (?)
================
Since the palm-rest is made of a "soft" material vs plastic, I wonder how it might hold up over time. Will it wear out? Time will tell.
