This is the first time I use an electric tooth brush. You really see the difference between a manual tooth brush, we feel the cleanliness, the teeth are smooth as if I had to go out to the dentist. Do not abuse, 2 times a day is enough. Rotations are fast, the downside: brush vibration (unpleasant) ca scared me for my teeth, can be after that I do not usually, and it makes a bit of noise anyway, so j 'removes a star to ca. Quick and careful delivery.
