I ordered this item and received a defective unit. Like other reviewers, the "1" slot bulb would not light up and I ran some tests swapping bulbs and power supplies (I have two ad200's) to see if the problem was with the AD-B2. No problem, I sent it back and they sent me a replacement quickly. Upon opening the new device, I immediately tried to light the lightbulb in slot "1" and again it didn't work. An identical defective device was sent to me. I don't know if Godox made a large batch of defective units and this particular seller is trying to offload them or something, but I returned the second defective unit and ordered a new one from a different seller. If this new one is fully functional as it should be then I will change my rating and review but at this point it seems incredible to me that I can't get a device that works at full capacity.
