Off-camera flash has evolved a lot since I bought my first hotshoe flash a dozen years ago. This little device is pretty brilliant, really. In exchange for doing away with the hotshoe mount entirely you get a sturdy builtin (but removable) umbrella stand adapter. Its form-factor is extremely well thought out and it's super flexible and adaptable as well as looking and feeling solid. It amounts to being a very capable mini strobe.
- 1/10th stop power adjustment is a godsend
- well integrated with the Godox XPro remote trigger
- modifier attachments (gels, grids, domes, etc.) are trivially added or removed magnetically, and can be stacked
- fits nicely into the S2 Bowens mount bracket adapter
- very fast recycling; beep is really nice
Not so good:
- I experienced some mis-fires (2.5%) -- this seems to be compatibility issues between the XPro-P trigger and my Pentax body though
- tiny, hard to read text on buttons and body -- I can't use this thing by feel; I have to wear my reading glasses to use it
- as shipped, the two knobs on the umbrella adapter can and do interfere with each other turning at any angle of the knuckle -- readily fixed by shifting the baby pin knob to the opposite side of socket.
- it took me a while to find the manual which is tucked into the almost completely opaque pocket in the lid of its travelling case.
I used it in a StrobePro 25 inch beauty dish + grid, Bowens speedring, installed in the S2 Godox adapter. Despite shooting 80 frames at 1/4 power fairly quickly the fan never came on and it stayed pretty cool. See attached photo. f/4, 1/125th sec, ISO 100.
When it comes time to upgrade my other older flashes I will definitely be getting more of these little units.
