I like this brush, it is practical with its rotating spin, so no effort to make, but beware, the heads sometimes do not fit the handle. And when we buy replacement heads, we do not always fall on the heads that fit sleeves. It is in my case. I bought the complete kit and 2 spare heads. The head initially sold with the kit worked 4 weeks. Then I replaced the head by one of the replacement heads that I bought, only in the 2 heads of spare I bought, one of them does not fit. So it remains for me only to 3. I'll have to recommend a set of 2 spare heads. But it will again be the lottery, because we can not know if the two will fit. And return periods are shorter. What is my case, I can not go back my articles. So that's my pear !!!
