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 Bag

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.

Best tens unit I've ever owned (out of 4) while being incredibly cheap. Pretty good range of patterns and very good granular control of the power level (no big jumps between levels like my last model). Sturdy construction, physical buttons are easier to use/more reliable than touchscreen models, charges quickly, and the default cords and pads are high quality.Been using for about 2 weeks now with zero complaints. It also survived being dropped on tile floor.

Researched many units!!This gem goes beyond it's performance 👍Sticky pads are SUPER sticky, even after consistent usage! Being able to recharge the unit is a PLUS. It's compact size makes it extremely easy to carry in your pocket without getting damaged.Would HIGHLY recommend 👍

I've owned several tens units over the years, but this one is my favorite. The charge on it is great. I've used it at least 8 times so far and the battery is showing as completely full. I like that the screen highlights the area each mode is for and that there are different modes for the same area. I also like that they included a little booklet with tips for pad application. It came with a good amount of each size of pad. The only negative I've found so far is the small pads do not have a spot without glue. On the medium and large pads, there's a white area where there's no glue to make the pad easy to pull off, but the little pads don't have that. Aside from that, this is a great device and I highly recommend it.

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.

Any athlete will benefit from this simple little gadget! Loves the ease of using it. Not complicated directions and the benefits are amazing. Love these variety of settings and the different combinations of vibrations. It aided 100% in pain relief for distance runners. Helped make muscle soreness less and helped aid in the recovery of a stress fracture in a foot.

LOVE LOVE LOVE this EMS unit. Battery lasts a long time. Lots of pads that have lasted longer than I expected. Relatively easy to understand. Let's hope it helps.
