I had a oral B and my wife has a philips 9300. We both feel that our e-brushes kind of hurt our teeth because we feel uncomfortable when we brush our teeth. We bought this because it was cheap, and we were trying to find something cheap for our memorial day trip. We didn't expect this to work sooooo well! Very good battery life, the speed is just perfect. No noise, and I feel much more comfortable using this than using my oral B. I am considering using it even at home. Will keep using it for while and see if it is durable. So far I love it.
