I have very fine and thin hair and was looking for a way to reinzubekommen some volume. In other reviews I've read that this rotating brush makes the hair partially electrically, from what I had also a little afraid, because my hair like to tend. Luckily it did not happen! Am really satisfied! To get a perfect look, really have to take a little more time, but if it is to go fast times, one has at least smoother hair. The other essays I can not comment because I have not used this, alas! If the rotating round brush recommend again for fine hair.
