I have no idea how I brushed my teeth before my Oral B! I bought this cause my dentist recommended I get an electric tooth brush, and this was a great investment. I was able to purchase this using a coupon, and it was one of the best purchases I've made. It cleans so well, that I almost don't really need to think about how to brush my teeth. It has a timer so I hit every quadrant equally, and gets the tough plaque my manual tooth brush could never get. Highly recommend!
