I compare with the usual "sonic" electric brush, a review of the color carbon, where there is a switchable vibration. For such a price, you expect ergonomics, well, at least not worse than the "sonic", but it is worse, and radically.
Its pros:
Maybe she's cleaning. But due to the general inconvenience of using, I would rather use a simple electric brush.
Cons:
* Works only with special pastes
* 4 times more expensive than a "sonic" brush
* Uncomfortable grip
* Not waterproof
* No protective capsSee full review
