Comfortable but becomes itchy.
I chose these pads because thirty years ago, had a TENS unit and would break out in hives the size of the pads. I find these pads very comfortable and last a while. However, if I wear them for an entire day, my skin will start to itch under the pads and when I take them off, I can feel tiny bumps on the skin but don't actually see a rash. I will keep using them because I need the TENS unit to control my back pain.
