This epilator is very easy to use since it is sufficient to activate a button to flash the skin. It should operate through against a pre-intensity adjustment before use depending on skin type. It is not suitable for certain skin types (dark, red ...). We must also remember to recharge it before use and to shave the hair prior to shaving. What is more difficult is to make sure I pass on all zones flash. Indeed, as the window that emits flashes is rather small, it is not on good cover everything, but the problem is the same with all the epilator of this type. They advise to draw lines with a white pencil on the parts of tweezers for benchmarks; it's a bit tedious side ... I think it's mostly a matter of habit. The epilator comes with several heads adapted to different body depilatory (legs, bikini etc ...). You still have to know that the flashes are not painless because every time feels a slight tingling sensation but it is nothing compared to a conventional hair removal. As for effectiveness, I'll tell it to you later because it takes several sessions to see the change normally. So I put this opinion to date over time. Anyway, for now, I am quite happy with this.
