In effect and price excessive.

I have a few months using the depth-cleaning bristles instead of the traditional Precision Clean bristles and could not detect any differences that would have been so significant that they justify the significant price difference. One should not ignore led that not everyone supposed progress on science but on a thoroughly-profit innovation pressure is also grounded.

These brush heads do not replace the repeated brushing a day, nor the cleaning between the teeth with dental floss or dental tape. However, if one does that anyway every day, then it could do basically any conventional Zahbürste also; either the teeth are cleaned or not.

In my opinion, can be reached by Precision Clean-Aufsteckkopf who has no yellow fins more brush, the same cleaning effect. I also have the impression that the slightly enlarged brush head and the additional mechanical parts have a negative impact on the oscillation.
