Works wonders for my chronic back & shoulder pain, and even pain associated with endo. So glad I decided to try this unit. It is just as powerful as the one my mother received from her physical therapist's office. Very easy to use and I was very happy it comes with it's own carrying case. The unit is surprisingly light-weight and comes with leads, electrode sticky pads, battery, and charger. The device shuts off after a set amount of time so you don't have to worry about falling asleep with it on. Charges on standard usb charger. Easy for discreet wearing. I clip it onto the side of my pants and wear a long shirt to cover it. It does beep, but I haven't figured out yet if there's a way to shut the sound off. That's the only downside in my opinion. Arrived super quick. I was thankful for the one day shipping option because of the amount of pain I was in at the time of ordering. I still have to take pain meds, but not as frequently. It is a great supplement to my current pain management regimen. Very good value if you would like a tens and your insurance doesn't cover it.
