A month ago I came across to this fabulous gadget and since I bought this amazing product I was asking my self why I havent done it before. I spent all my life brushing with normal tooth brushes and never experienced the sense of cleaniness and freshness as much as I do now by using the Oral-B Genius 8000 . I experienced for the very first time the difference in using a Rechargeable Toothbrush. This toothbrush has an application connected to your smartphone to guidance you brush every section of your teeth, just like when you are at the dentist. 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. Oral-B Genius 8000 has also the function to monitor the strenght used when brushing and it vibrates to show you its time to change section. With the use of this amazing gadget Oral -B Genius 8000 brushing my teeth is more fun and it is highly recomended for all ages and all the family members.. I am in love with this intellingent and amazing product. Well done Oral-B and Braun.
