I love it. It's helping with all my pain. You can use it while it's plugged in or after you charge it. I used it for over three hours, an hour at a time, with one charge. The tens part is handy and helps my back a lot. I'm glad I took a chance.
Excellent therapy for my feet and lower legs. I have a sciatic problem which affects my feet when I walk or stand in one place too long. This treatment helps revitalize my nerve endings and my circulation. I had a previous model and it was great until I had two cats that decided to scratch the surface of my unit. When that happened it was shocking my feet, so I replaced it with a new one.
