I would like to add that this TENS unit is a piece of garbage. With that said, it is 'better than nothing'. I bought this on another site about a year ago for a total of $27 shipped. If you have ever visited a physical therapist or chiropractor then you are familiar with their $200+ TENS systems which is magnificent. This is probably just a matter of getting what you pay for, but I believe this goes up to a 10 level, however, I can barely tap it to get it to level 1 (a small step up from the on switch) and it shocks the crap out of me. I have read that when the pads go bad this could happen, however, this product has felt this way from day one. I ended up buy another brand that is made better. I still have this and use it from time to time but I would recommend holding out for one that is a little bit more expensive, you get what you pay for.
