I have multiple, never a problem (2nd gen only, never tried the originals). Sorry. No help to the OP issue, haven't had any problems. Just FYI for anyone else looking at these: Good connectivity, pairs right up and battery life has been way better than expected. They're not silent, you hear the motor and then a plastic on plastic slap as the switch hits the far plate. A few seconds with a Dremel got rid of that last noise, but you still hear the motor. I don't use these around where the family spends time, but they're good in the shop, garage, shed, laundry room and spaces like that. Living Room? No way.
