So far I have purchased four of these units. One for myself and three more as gifts for family members and friends. I highly recommend it to others who are interested in this type machine.

I'm VERY pleased at the quality and function of this little unit!! I just didn't believe something that ran on batteries could ever be strong enough, but it iis!

I ordered this unit after having TENS treatments at my chiropractor's office. I was happy to see that this small unit delivers the same massage as the commercial ones used by doctors. Overall, this is a really useful and effective little machine!

After taking a long trip with my wife and uncle to the north shore of Minnesota(2015), the days of driving took their toll. Stiff back, neck pain, the usual. Personally, I have only gone to a chiropractor three times previous to this and he used one of these units along with a heating pad to loosen up my muscles. My uncle happened to have his unit with him and let me try it. After only 5 minutes, I could feel it begin to work and bring relief. With 20 minutes of use, my back and neck were 85% better. I recommend getting one of these units to help with your back issues, where NSIDs don't/won't work.

Received this item yesterday, watch the videos on usage and put it to work on my knee. I varied the speed and intensity and I could really feel it working on the sore muscles and pain I've been experiencing. It is easy to set up, easy to use and really made my aching knee feel much better. I have a right hip issue that will receive the next treatment. My regret? Not ordering it sooner!!!!!
