In the beginning it worked fine, after several uses, in daylight photoshoots it started to fail, the problem is that when it starts to fail only one of the flashes/bulbs works ie need to switch their positions (bulbs and AD200) to get both bulbs working again. I know AD200 has heat protection but when you use this adb2 adapter it fires too soon, not even after 10 minutes of use or 20 flashes. and it starts to fail, i don't see any warning on the ad200 screen, i have read the manual for the temperature problem but not sure if it is the problem, when using the ad200 alone they work fine and never have get a high temperature warning or something like that. Even with the above problem I still use it, it works the way I labeled bulbs and ad200 (e.g. bulb 1 plugged into slot 2, bulb 2 into slot 1). The LEDs work perfectly, I had to epoxidize both plastic LEDs as they easily come loose on contact with the tripods in the tripod bag I use. I can't return it as I don't live in the US and it would be cheaper to just buy another one.
