TENS Unit Muscle Stimulator for Pain Relief Therapy, 22 Modes EMS TENS Machine, Electronic Muscle Relaxer for Shoulder Pain Relief, Back Pain, Shoulder Neck Pain Relief

I bought this primarily to deal with tight lower back muscles and shoulder tension after long work shifts at my desk, and it has been working out really well. I wasn't expecting much given how lightweight the unit is, but the intensity levels actually carry a serious pulse. Setting it up right out of the box took less than two minutes. The controls are simple to navigate, and I really like that the rechargeable battery holds a charge for several sessions before needing to be plugged back in. The electrode pads stick well, though I found putting a tiny drop of water on them before applying helps them stick even better after a few uses. It easily slips into a pocket so I can walk around the apartment with it on while doing chores. Overall, a super practical tool to have on hand for routine muscle aches. Definitely recommended!

It played a big part in waking up my quads after ACL surgery

very helpful especially when you work out every day

Seems to work well. Charges via USB-C instead of taking batteries. Settings take a minute to figure out, as the manual is not super clear on how to work them all, but it's pretty easy to figure out.

As I have major back pain coming off of kidney surgery and my back isn't quite right. This TENS unit has been an everyday fixture for me and it is definitely worth it. Would highly recommend it to anyone. Just make sure you get the right pads for reuse. Also be careful about how you store the cords because they will eventually short out so you will have to go back on here and buy replacements.

Funcionan bien y son fácil de usar

Was able to use it for a weekend and wasn’t able to charge it right away recharged it just now about a month and a half later and now it won’t turn on at all

For a pre programmed unit, it works well. Battery life is good. I’ve used it more than 10x for multiple 30 minute session and still have 3 of 4 bars charge showing. Stim output is plenty strong. Back light is very bright but the buttons are not illuminated. CONS: Supplied electrodes don’t stick on my hairy carcass very well so I use another brand. Cords are far too short. I’m 6-0’ tall and they will barely reach to my knees if I put the controller in my pocket. Same issue for shoulders and arms. Luckily, I have long leads from other units that interchange easily. So, if you’re smooth and short and/or have extra pads and cords on hand, the unit is fine. Otherwise, for $40, you might be a bit disappointed as was I.
