Awesome! Ended up getting two!
5/13/2025: Still going strong. For anyone wondering if there are any issues or something to look out for. The lowest flash setting is at 1/16. This may or may not be a deal breaker. If you're shooting wide open at f/2.8 sometimes even with the lowest ISO (50 on my Sony), it can be too bright on product shots and need to use an ND filter.
Also, this does not have HSS so with my a7R V at least, I can only shoot up to 1/160 before I see the dark strips near the top at 1/200.
1/25/2024: I recently purchased Godox XProC II transmitter for my Sony and it works seamlessly with this strobe. In fact, the XPorC II transmitter works better with the strobes as it doesn't jibe with their V860II hotshoe flash (hit or a miss).
I'm a full-time professional corporate photographer and videographer. I've had everything from Speedlite's to inexpensive versions of non-branded hotshoe flash, which I still use. Still, after not having a dedicated studio flash for some time, I needed one to not worry about batteries and be able to take photos quickly.
I already have the Godox XPro-C wireless transmitter with Godox V860II, which also worked simultaneously with this SK400II. But after having it for less than a month, I decided that for this price, it was a no-brainer to have another and not bother with the battery.
I mainly use this for product photography, which I often do for my job. I rarely go above 1/8 of power, and with the second one I just got, I'll have the fill light to be less than that. The light is more spread, unlike the speedlights mounted on an adapter. It fires consistently, and there are no issues with overheating.
Combined with a 36~48" softbox, I can easily make either a dark or white background with my thunder grey paper background. It is more pronounced when using a honeycomb grid to control the light spill.
Unless I'm trying to overpower the sun during the day or daytime portrait shoot, this has more than enough light with plenty of overhead.
Keep in mind, the minimum output power for this strobe is 1/16, which may be too bright for certain applications. Godox has the 400W, but that can go as low as 1/64, which may be better for fit for certain applications.
