Thanks to this toothbrush, I discovered a fun way to brush my teeth. Brushing is complete and the brush vibrates whenever switching to "corner". The many brushes available allow to use several different modes. The timer is convenient even if through "vibrations" after some time looking at the longer even. The brush design is very nice and the "travel box". The brush takes up more space than a toothbrush, obviously, but it's worth it! It is true that at the price, it is an investment, but I think it's a long term investment! I recommend it without worry.
