When you first try I was pleasantly surprised, the brush head is significantly greater than that of Oral B and obviously worked well. Unfortunately, the first brush broke after two use. Of the two brushes turned only the bottom. Of course, just is the broken important because only this good comes to the back teeth. The other held between one and four days. After four weeks, all eight were broken. It is possible that some customers have not noticed and brush satisfied only the front teeth, for me that is not enough, however.
