TENS Unit Muscle Stimulator,Dual Channel,Upgrade 6 Modes 20 Levels Intensity,Compact and Rechargeable TENS EMS Machine for Pain Relief,One-Key Intensity Control for Physical Therapy Shoulder Recovery

Love this tense unit. I got this one for my son and had never used one. I tried his and we both loved it so I bought one for myself. Use it all the time for sore muscles, stiff neck, back pain and arthritics knees.

Simply works, best one for the money, have used others, but the small size I use in my pocket on the golf course, and I am a physician and there is no basis to the manual saying limit treatment for 20 min a day, I use for 5 or more 20 min sessions, if it had a way to set for 1 hour I would use that.

Tiny, but useful!

Will not take a charge at all, piece of junk

Works great, definitely one of the better tens machines

It works but not as well as other brands I have used. Battery life is good.

Small unit.simple operation.effective.good price.good assortment of pads.everything I wanted. durability and lifespan unknown.

works great
