Skin Reaction to Pad
I have never had a skin reaction to materials before - and have used a TENS unit for a few years.  I purchased these pads because of the price and size... however the evening after using them I had bumpy red marks (identical in shape, size, etc to the pads) almost as if I had been burned.  It has been nearly a week - and while the bumpiness has disappeared, the skin is still red and feels dry.  (There is a picture that someone else posted showing red marks - that is similar to how my skin reacted)  I don't like leaving negative comments - but feel this is warranted.  Just be careful - if you purchase these, test them on your skin for a short time to make sure you don't have the same reaction.  Very disappointed with this purchase and will search for a product with better reviews.
