Great portable tens unit for back pain relief. Easy to use, quick to set up and battery life seems to be quite long. I like that there is a little cover over the controls so you don't accidentally turn up the intensity and shock yourself. Quality is nice and it was affordable too. I had lower back pain that was persistent but using this for a few treatments seemed to do the trick. This is one of those things you want to have in your medicine cabinet on hand just in case you need it in the future.

My right shoulder is usually sore after I get up in the mornings and this little unit makes it feel better. My first experience with electrical nerve therapy was at the chiropractor and it really helped my back. Having something similar at home in between visits is great! It is very easy to use. It has 5 modes of pulses, and I really only use 2 to 3 of them. I looked at other units with a lot more modes and not sure I would need that many. I have the unit that is rechargeable and it works well. I charged it up the first day I got it and have used it almost every day for 30 minutes and still has a lot of battery left after 7 days. I’m very happy with it and would recommend to anyone.

This unit is perfect!! I purchased this because of the charge feature by USB vs. batteries. My previous unit is 12+ years old. So excited for the new updated technology!

Works well, it’s not as powerful as my old one, but gets the job done

This thing is amazing. Feels just as good if not better than the kind used at a chiropractor. The charge holds for a lot of use time and the ease of being able to create and save your own custom patterns is perfect. I would recommend buying some additional electrodes with it and if you’re on the fence, don’t be. Mine has worked flawlessly since initial the initial purchase.

Great product, i had a crazy back and hips muscle pain after using it couple of time I don’t have pain anymore

I had a much much older one and it worked great. This one was rechargable and didnt make me find 9 volt batteries to run.

Still using on the paralyzed side great quality lightweight reminds me of the one that was in the hospital but I believe it's stronger you need a jump start again this is the item
