A good little toothbrush famous brand Oral-B. Ergonomic grip, its small size allows lemmener without problem in a small travel kit. As for autonomy is also very good. I can brush my teeth because of 2x / day for one week without problem, against the loading time is very long (Ni-MH technology requires). However, the small base of waterproof charging induction makes me forget this problem quickly. Use level we feel a distinct difference before and after brushing the teeth appear more smooth and clean. The timer can be convenient but futile if do not brush their teeth into "quadrants" (ie brushing his teeth in his mouth dividing into 4 parts). The different bosses offered by the brand are of good quality but quite expensive anyway! (There are already supplied with a toothbrush if I'm not mistaken). There is no maintains to the toothbrush. You just rinse thoroughly with water after brushing (just count 3 minutes to brush your teeth in the end being reserved for 1 minute wash).
Negative side I note the following: The noise is very present, and becomes problematic if people are sleeping and that we are up late! (Which earned him the withdrawal of a star). Dry thoroughly to prevent deposits from forming at the charging base by cons!
I use it for 1 year and I have not had any problems at the product itself. I recommend.
