Brushes interesting technology but overpriced.

Technology: Philips says that with more than 31 000 movements per second, this brush with a brush DiamondClean removes up to 100% of the spots in 7 days. Not having spot, I have not been able to verify this assertion. But 31,000 movements, it's still impressive!

Vibrations: This brush does not work the same way as other electric toothbrushes. Allow a few days to adapt (I put the same time to adjust to my first electric brush). Note that the brush itself suits your habits in 7 days (14 brushings).
