Review (4/5): Great brush!
This brush is great. The spin head is great at scrubbing your teeth and the brush is ultra-durable. The battery is the only thing that I think needs improvement. I've had mine for about three years and it's still strong. The only thing is that from time to time, although it's fully-charged, it won't turn on. I've found that all one has to do is "jump start" it to get it to work. Just put the brush in the on position and repeatedly pop it into the charger port until it turns on.
