After trying to figure out how to use this TENS unit I have to say that it's not for the beginner. That's probably because it's very customizable and therefore complicated. I would recommend that you find someone familiar with using TENS unit like a physical therapist to get some help with it. I also noticed that sometimes it doesn't make good contact but maybe I just need new pads.
My mom had back surgery years ago and still suffers daily from pain. I bought this for an early Christmas present and she says just using this twice so far has brought her such relief. Great product for pain management!
