The cleaning performance is my previous Oral-B by a mile in the shade. The half-minute vibration that recalled now to change quadrants one, is a big help. In addition, the app which the one brushing habits unvarnished mind keeps in my eyes a novelty that I do not know so. Therefore, I am still quite curious and reflective my grooming behavior and draw my conclusions. In addition, it can be said that feel the teeth, especially in the poor reach areas even after the first application of clean and that feeling lasts longer. All in all a clear benefit that justifies its price. Especially as an electric toothbrush not even a year you can buy. And there in the station up to 4 Zahnbürstenausätze can be stored (ie four members of the household), the price into perspective, ideally again.
