AUVON Rechargeable TENS Unit Muscle Stimulator for Back Pain Relief, 600 mAh Battery TENS Machine with 8 Customizable Modes, Stim Machine for Shoulder & Neck Pain Relief, Nerve Pain Relief, 4 Pads

This unit is great. It lasts a very long time on a single charge and is very powerful. I use it a lot on my back and shoulders and my son does also. It really works for relaxing muscle spasms.

very good, the tens device and some extra pads cost less than the CBD i tried and works much better than the CBD also! I did have a Tens used on me before so i Know they work i would suggest you get a book for using these they have one on amazon and its good also! the device works well the pads stick well also and you can get replacement leads also from the manufacture.

Shipped fast....it was value more than what I paid for it....Eady instructions....portable to wear /use anywhere.... rechargeable....overall Excellent purchase.

East to carry. But could use a bit more power. Overall not bad

A nice TENS unit. It has sufficient power for any use and is easy to use. While the instructions are a little sparse, a little easy exploration of the settings will be sufficient to use the device.

Works very well. Excellent battery life. Silent.

Works has to be fully charged.

Good product
