The strobe itself is excellent, I bought 2x300 and 2x400, the light is very balanced AND stable. Never seen it get hot and its receivers work flawlessly with the triggers Godox offers. My biggest problem is that one out of 300 failed after about 3 weeks. OK, it happens. but repair became a problem. Godox would exchange but I had to ship to China first. Buy new cheaper. I bought a 3 year replacement warranty but they refused to honor it because it was under an unenforceable warranty from Godox.
