3-in-1 TENS Unit Muscle Stimulator with 30 Modes, 40 Intensities TENS Machine for Gradual Back Pain Relief Therapy, Rechargeable EMS Unit Massager with 12 TENS Electrode Pads, a Storage BagCarbonfree Certified

I am blown away by the quality of this inexpensive devise. Not only does it work well but the features and ease of use is amazing. If you turn up the intensity it can deliver unbelievable results, and I cannot turn it up nearly to its capacity. After 30 minutes of therapy, I plug the unit into my laptop, and it is fully charged less than five minutes suggesting a superior lithium battery. I cannot express how thrilled I am with this purchase.

I have issues with various parts of my body, in particular my back. I bought a different TENS unit some time ago and this one beats it all to heck. My old unit had only twelve modes and I didn't realize it was not real powerful until I got this Avcoo stimulator. I particularly like the EMS massage modes and find them very effective. I have often thought that I would like to have a stimulator that I could program myself to get it just right. With this stimulator I have found what I was looking for without needing to program it myself. I like the pads that came with the unit as they stick better and are more reusable than those which had on hand. Also, this unit lets me use it for 90 minutes. I rarely need this much time but I really appreciate it when I need it. At this price, I consider this to be a bargain.

This unit may be small, but it packs a punch. I've used a few TENS units before, and I can confidently say this one performs on par with the larger machine at my chiropractor’s office. When shopping for items like this on Amazon, I don’t focus too much on price—sometimes the more affordable options turn out to be just as good, if not better, than the expensive ones. My advice: read the product descriptions carefully and pay attention to real user reviews. In my experience, this TENS unit is absolutely worth the cost.

But works great, box came damaged

I am very happy with this small tens unit. It delivers great relief dependably. Thus far, I have charged it the initial time, have used it at least 8 times and it’s still going strong. The sticky pads are great, can reuse many times. At a reasonable price, I would tell anyone looking for a unit to get this one.

I use is on my back. My back is kind of a mess. These have multiple settings, which makes it perfect for me. The relief on my back that I get from this equipment is great. I know there’s many of these out there. I’m lucky I found this one little research. I’ve been using this for a month and I’ve charged it once. I hope they can work for you if you try them thank you.

This is the second one I've bought. I dropped the first one and it ruined the screen, but it still works. Forget the amazing price, it's small, but strong. It's very easy to use and I love all the options and settings it comes with. The battery lasts a very long time. As long as they don't raise the price, I will always come back to this unit.

I have a lot of back issues, and my old tens unit was getting out dated, so I wanted to find a new one for a good value for price. This one had good reviews so I went with it. I am not disappointed at all. It works well.
