We have had one transformer in a whole lot of T2's go bad, so I would not say it's any sort of epidemic. A bigger problem was with IR output, but from what I can tell that seems to have passed. Either problem was immediately taken care of with replacements by RTI.
Several customers called because their new T2 Battery won't charge, when I ask them if they removed the sticker on the contacts they are always a bit embarrassed. I have to admit I did it the first time also, they need some sort of large “remove before flight” streamer on these.
