This device is really effective! I feel at lesthéticienne! I tried virtually all brands of supermarkets and it is not torn anything, it is cooled too fast and in any case I suffered martyrdom! With hard wax in roller (to use tapeless) any pulls and does not suffer (at least less than any other wax and much less than the epilator for those who use it) because it is a soft wax and the device allows it to be always at the right temperature. With soft wax (one in the pot. The pot is inserted directly into the machine and not it does not melt even with the heat!) For use with tapes (ideal for legs) while nickel is removed without need 'return 20 times. Frankly I regret not having known this machine before it would have me avoid many fees!
