If they would only fix the battery issue
Really a very good toothbrush. I just wish they would put a longer lasting rechargeable battery into them. I really dislike having to go out and replace the entire unit every year or so because the battery stops holding a charge. Instead of making them Bluetooth active, how about a replaceable rechargeable battery instead??
