Lost the pads that came with my TENS unit or should I be honest here and state that my son lost them on me when borrowing my unit, but anyway :D...I was really happy to get these in as I have missed being able to use my machine. These pads stuck well to my skin but were not hard to peel off either. I was worried after reading a few reviews that they were not compatable with some TENS units but they worked well with mine and I was back to being able to use it! #RankBoosterReview
