For more than a month I use full satisfaction this electric toothbrush. I must say that this is also my first electric toothbrush ever. But I think just for people like me, this model is suitable: beginners, first-time users, Ausprobierer. And according to this month of use, I realize that my teeth are generally clean. So quite lied advertising actually seems not to be - obviously you get more than the conventional scrubbing (even if it is thorough), not the result as an electric toothbrush. The battery has never let me down, although I occasionally connect the station to the outlet. The brush head is removable and replacement of course can be had for relatively little money. That both the entire brush have nothing against water touches absolute, is self-evident - only for cleaning purposes. I especially like the fact that the brush is an audible and perceptible signs (briefly altered vibration) to show that for half a minute has elapsed time. In a division of the teeth in the mouth into 4 quadrants one is so well scrubbed after 2 minutes by mouth. I recommend this toothbrush further definitely. The last star it therefore does not get, because the station but not very robust and works because it all in all, but is considerably more expensive than a conventional toothbrush.
