A fantastic option for location/wedding photographers. I cannot recommend this unit enough. It performed flawlessly on every shoot I have taken it on for the past few weeks, and I'm already looking at getting another one! In this price range, I don't generally expect quality-built equipment, but Godox has been proven us wrong time and time again. The mounts on the sides of the flash are solid and don't give at all when the flash is mounted to a stand. The best of all for me is the battery, airports check my bag without fail, when I travel with the AD200, they haven't batted an eyelid yet. This is great for us phototravellers. The AD200 has both TTL and HSS support through the Godox trigger system. Both work flawlessly with my Nikon D750 and the Godox XT32n trigger. TTL is accurate, and the unit switches automatically to HSS when the shutter gets over 1/160.
