I was a little skeptical of this new system, and then ... and then, I find it really well :-)
The brush faithfully reproduces the movement recommended by generations of dentists: a movement from the top down. in use, unless it tickles the rotating brush, but it cleans just as well.
A big plus compared to my usual brush: the light pressure sensor, it is really well thought out. Very simple: the LED lights up if you press too hard, a way to remember that you do not need to attack your gums for healthy teeth. recommended especially to those who turn their brushes daisies in less than two weeks (I know).
Aesthetically, this brush does not differ from other models in the Braun Oral-B, it is also compatible with rotating brushes trizone if you do not like.
One downside: the price! almost 90, it's getting expensive, even if it makes you run to avoid dental expenses.
