20000 beats per minute!

... Or 8800 rotations per minute tilt-ca ... I can not make manual brushing!
This electric toothbrush is very well designed, well equipped and efficient, for a price that is relatively reasonable (when compared to the more advanced models that exceed the 150).
Well designed: it is ergonomic, Good grip, Easy to use. Compared to other models, it takes up little space; This is significant for small bathrooms.
Well equipped: The brushing time is controlled (signal every 30 s for changing quadrant), the pressure is controlled and there is a battery charge indicator.
Performance: The result is up, cleaning is obviously effective, and battery life is relatively long (about a week for individual use).
For all this, the price seems to me appropriate and this is an article that I recommend.
