I haven’t read this entire thread but I vaguely remember at the end of last year I was reading reports about the BBs people were building at Droid Depot saying every time they wanted to use the BB they had to open the unit and turn it on. We built two BBs last October and encountered the same issue, we couldn’t simply turn on the remote and start using the BB, we had to open them up and toggle the on switch and sometimes re-pair the remote. Recently when using the BBs they’d turn on and work for about a minute and then “fall asleep” in the middle of active use. Apparently their “motivators” aren’t working anymore so at this point they can’t even be used. Not sure if anyone else has had this problem but it’s somewhat frustrating for an item that isn’t even a year old.
