Very efficient but very painful. This is an epilator that works as dozens of tweezers. it turns it turns and it tears. We can not say that it is nice but not unbearable it is not a cakewalk. The only real alternative to the pain it is to do it in the shower. Here it loses a little speed but there really wins at the torture session. This is much more easily bearable but it's still unpleasant. The small integrated loupiotte facilitates verification of eradication with less shade. As for the promise of the 4 weeks of tranquility that will depend mostly on your hair system. A good product if you want to be handsome or beautiful. Oops: And if you want to suffer is a good product too! :-))
