The settings don't work. I keep it set at 7 bars & it continually resets to 1 bar. Very disappointed in this product. I'm returning it for a 1 time exchange. Hopefully it will work better.. The replacement has the same problem. My son-in-law bought me a much better tens massager for Christmas that I'm very pleased with!

I bought 2 of these and probably won't buy another, I had this product for about a week before one of them stopped charging completely I am very dissapointed with it for that reason WHEN it worked it was very nice

never worked, i am so sad, this os terrible, yall best stay away from this.

The day that I received this product in the mail I tried to use it and it wouldn’t so much as come on. It was a terrible disappointment and I don’t trust buying another.

The TENS unit was feeling alright until the forth time i had it on while using it, it stopped working! The three previous times i just sat in my recliner, the forth laying down. Did all the trouble shooting requirements, just stopped working! Had high stars when looking for a unit, guess not!

total garbage, no power at all

This worked good but quit after only a month

It is a dud!! Does not work at all. Intensity at highest level and I felt nothing!!!!

The unit it's self works great, but after 2 uses the display on the screen stopped working. It still works just no display.

Very disappointing, worked one time and then stopped working. I’ll be returning it. Don’t waste your money! Spend that on a real massage :)
