Wonderful light, solid build and provides the speed for my high speed commercial work. Love the fact that these have the colour stable modes as well!

I really wanted to love these lights (I got two qt600iii and two qt400iii). We'll start with the bad:- Upon their arrival I noticed that they are much heavier than I expected - it speaks of build quality to an extent, but also makes them less comfortable to work with on booms and arms, requiring more sandbags.- After a few shoots I can say that Godox could (and should for the price) have done better. Yes, I get occasional misfires, not a complete disaster. The thing that drives me absolutely bonkers is that they sometimes fire at full power while clearly not set to such. No idea how to remedy that.- Also, and this is something I should have researched before my purchase, they need to be purge-fired when the settings are changed, or they will fire at previous ... MoreI really wanted to love these lights (I got two qt600iii and two qt400iii).

Most other lights I worked with either silently purged, or autopurged when the setting was lowered.- The menus are not quite clear, with a bunch of settings in mystery-meat submenus without any indication what they might mean. Must always refer to manuals. There are too many buttons, they can clearly do with less.- They are loud (POP!) when they fire, even at lower settings.The better:- Fast recycle- Consistent color when in color mode- Great modeling lights!Generally speaking, I don't find these to be better than anything else I've used (in a range of price-points). Considering that this is a third gen product, I'm surprised at all the quirks and design choices. My search for lights will sadly continue.
