So far, I have four of the brush tested (one is thus still out). At first I thought that the difference between the brushes could not very well carry weight, but I see now different. It has been found that my teeth for the smaller brush heads are most suitable. My impression here is that they cleaned most thoroughly. In other words: the floss has then to do less.
In the future, I will decide accordingly for the small brush heads.
Who wants to find that attachment for her or him is the right should treat yourself to this five-pack. After trying out does indeed have some fun!
A deduction of points, however, there in my review of the pricing of the company Philips, because to ask about 5 euros for a brush head, I think simply for overpriced - especially in a large pack. That being said, there is nothing to complain about.
