AUVON Rechargeable Digital TENS Unit Muscle Stimulator with 600 mAh Battery, TENS Machine with 8 Customizable Modes, Electric Massager for Shoulder, Back Pain Relief, 6 TENS Pads, A Carry Case

By far the most functions of any tens units in its price range - solid performance and quality lead wires and pads make this a safe purchase that should last for many years

Well made, easy to use and works great!!! This is the one for sure!!! I’m so happy I got it!

great tens unit and the price very affordable. The charge lasts a long time and is easily rechargable. The unit has different size pads that can be used for different areas of the body. It has really helped with my tight muscles to really work out tension. Definitely recommend.

Easy to use, rechargeable, light weight and mobile.

This was our second TENS unit since my husband lost the first. It has a lot more modes and options than our original - you should probably read and keep the directions around but we like the chaos in our house so we didn't. It is slightly confusing because of everything, if you're looking for a set time, hit start sort of model, you won't like this one. It works really well despite all the settings and we use it frequently when someone is sore has a muscle issue. This unit is strong for being so small. Start lower then work up!

Is very good machine I would like to buy it again

Works as well as the professional units at my physical therapy. It cold have better instructions in the manual explaining the settings but thru trial and error I figured thing out. I had to give it 5 out of 5 because it really delivers and the rechargeable feature beats having to keep batteries on hand. The charge level indicator is a great feature so you know whether you have enough power to complete your session. It's a convenient size, rugged enough, easy to adjust while it's operating. Overall best value I've seen for this type of device.

Yes I like having this available for sore n shift muscles
