[This review was collected as part of a promotion.] This product has certainly helped my dental hygiene with it's high performance! I was always the buy your manual toothbrush from the convenient store kind of guy. Since using the Oral B Genius 8000, I have seen a tremendous different it the visual and feeling with my teeth. The best feature by far is the ability to choose your setting for when brushing your teeth. I have very sensitive teeth, so the feather mode option is quite lovely as it brushes and brushes. The coolest feature is the ability to link to your iPhone app. The ability to track your brushes helps with seeing trends and data on your brushes. Certainly a must have product!
