I have gained this electric toothbrush because I easily attacked and very sensitive tooth necks of some teeth, so was recommended to me always slightly bent with the toothbrush from dentist to brush against the gum, which I also made some time manually so. Since overall relatively cumbersome (especially in the rear molars) is yet while respecting the need in a circular motion, a slight angle against the gums to brush each tooth individually and so I've decided to try once an electric toothbrush. I use the brush now for over 1 1/2 years and am completely satisfied that brushing has become much easier and the dentist was always satisfied with the interim controls both with plaster result, as well as vitality of the gums. The toothbrush has an additional built-in 2 minute timer that indicates the optimum brushing time (by pulsating movements of the brush head). Little hint yet: When I bought the brush you got registering the toothbrush on the Internet an additional one year warranty on the toothbrush (I'm not quite sure whether this action is still valid), thus with 3 years in my opinion, the average useful life should cover completely the electric toothbrush :) The toothbrush was Warentest test winner at Stiftung and outperformed products in the price range above 100th Although I was at first skeptical, I have to say here you get a really neat electric toothbrush, at a really reasonable and affordable price. From me a strong buy recommendation in particular for those who want to switch from a manual to an electric toothbrush.
