good idea bad implementation [SEP] as a woman in my s chest wrinkles are a concern i bought this thinking it was such a great idea it arrived fast and there are reusable silicone pads in individual sealed foil packages i am not sure if i do calisthenics in my sleep just have too oily of skin or if the pad just does not stay on even when i apply after showering and no lotion or powder on i wake up with it stuck to my shoulder or thigh some days the hunt for where it wound up is funnier than othersfor me i would not purchase this again
