After so many years using a normal manual toothbrush, I experienced for the very first time the difference in using a Rechargeable Toothbrush, the Oral-B Genius 8000 powered by Braun. I must admit that the cleaning experience that you get when washing your teeth with this intelligent device is totally different when compared with cleaning your teeth with a normal toothbrush. The feeling is like when cleaning your teeth at your dentist. Besides that when the rechargeable toothbrush is used with the Position Detection feature found in the Oral-B app on the smartphone, you will also be guided accordingly on how to wash your teeth more accurately. Definitely recommended to all persons irrespective of their age. Well done Oral-B & Braun
