Review (5/5): Reliable and Effective
I've been using the Philips Sonicare for years. I brush twice a day for two minutes and floss once a day and have not had any cavaties in that time. The things I like best about the Sonicare are the brushing action, 2-minute timer broken into 30-second intervals, and the ability to always maintain a full charge. The units wear out after a while though, which is not surprising for a rechargeable battery driven device.
