The precious legs system has a lovely result- smooth hairless skin and can presumably be used on other area of the body if it doesn't make you sore. The size of the discs is very small and takes a long time to cover your legs- although it gets into smaller area like underarm easily. There used to be a hand version of this disc. It fitted over the hand , covered area of about 3x4 inches and you just rubbed it over your legs in a circular motion. Just as effective, I have found nothing to go wrong and good exercise for your arms. Does anyone remember this too.?
