Tens Unit use electronic pulses to massage your muscles. It's helpful for muscles soreness, stiffness and chronic pain. This Tens Unit has 3 pre-set modes, and 6 pulse patterns labeled by the area of the body. (back, shoulder, neck, joints, hand-foot, arm-leg.) It has an intensity dial from 1-10, 1 being the lowest and 10 the highest. This allows you to control how intense the massage is, or use different intensities on different body parts at the same time. The unit has a backlit LED screen and runs on 4 AAA batteries. It comes with 4 re-usable electrode pads. The unit is about the size of a remote, small but powerful. After 2 weeks of daily use my muscles, my shoulder especially, are less tight and get sore less easily. If you have any kind of pain issues or just want a massage without paying an arm and a leg, i recommend a Tens Unit. You can find this awesome one by Easy@Home on amazon.
I received this item in exchange for my honest review from tomoson.com.
I never recommend products I don't like or use personally.
