ok so I bought this since my husband and I are trying to rekindle stuff. When I showed him he was terrified from the picture. We get it and I was like try it on you first I don't want to know how it feels until you use it on me, but want you conformable. Next day he says I tried it on my arm n omg you feel it in your nerves so he says watch and puts it on me in places. OMG this is a feeling I have never felt, it is not painful, is not sharp, did not leave marks, it is intense , arousing and awakens your nerve endings. I highly recommend!!!!
