Following a breakdown (previous Oral B toothbrush aged over 10 years ...), I had to buy a new brush. After some hesitation on the type of brush and attentive reading of other buyers comments on Amazon, I decided to test this brush trizone knowing that I can always use conventional rotating brushes. After a few days of use, I feel better than before cleaning. Only point which leads me to not put 5 stars, that only one brush is delivered with the brush, it's a little shabby!
