TENS Unit Muscle Stimulator, 24 Modes EMS Machine for Pain Relief Therapy/Pain Management, Rechargeable Electronic Pulse Massager with 2"x2" and 2"x4" Electrode Pads (Silver)

Purchased this unit during an Amazon Lightning sale and got a really good price on it. My wife had significant back problems in the past and had used a TENs unit to help with the pain. I recently started having back problems and we no longer had the TENs unit that my wife had used. When the unit arrived, my wife grabbed it and started using it on her back, her upper back, and her tennis elbow. She loves the unit and it was a challenge for me to get it back so I could use it on my lower back. I finally got it yesterday and put it on my back which was really hurting. The interface on it took a while to understand. But I found a setting that seemed reasonably comfortable and let it run for around 15 minutes. The sensations from the unit were interesting and I did not know what to expect. After I was done, I took the pads off and began my day. The pain situation seemed to be better and throughout my work day I did not have any significant back pain. The pain did not return until the late afternoon. I did try it on an ache on my shoulder and it did not seem to fix the dull ache (probable arthritis) but it may take some experimentation to find the right settings. As for the unit itself, it is very compact, looks nice and works quite well. It can even support to sets of pads on two separate wires at the same time. Really a very nice unit and a great unit for the price.

I really like this tens unit. I must admit I was skeptical at first but pleasantly surprised to find it to be as easy to use and as powerful as it is in such a tiny package. I have had one of these used on me in physical therapy before and this seems no different than the ones that they were using on me at the time, and I'm sure the devices they were using were much more expensive than this was. I haven't used the second pair simultaneously yet so I'm hoping that you can adjust the two pairs independently of each other. It is very simple to use which is nice. I can't speak to how the battery will hold up going forward. Only time will tell. I have had several surgeries in my ankle and legs and have suffered a bit from upper back, neck, and some minor shoulder pain. I am very happy to say that so far I have used this on my upper back and shoulder and have found it to give me quite a bit of relief from the pain in those specific areas. It doesn't last for days but it certainly helps a lot and who knows maybe after long term continuous use that will change. I have already recommended the device to several people that I know who could benefit from using this. I only have a couple of small complaints. First, the instructions could be more clear. In multiple places on the site page and the manual it mentions that the device is great from relieving neck pain, yet at the same time the manual warns the user against using it on the neck. So I'm not sure how I'm supposed to use it to relieve my neck pain. Also I wish the modes were listed as words on the device not the pictures. It would be much easier to use if you could toggle through the modes and just see the name of each one. Thanks. Overall great product with a little room for some improvement.

This is the perfect TENS unit to have at home. It works just as well, if not better than some of the higher priced ones that you can find on the internet. Works super well for period cramps and tense muscles in the body. The battery life has been great, too! I can get a couple of days in before it drops one bar. Giving 4 stars only because my only con is that I wish the pads were a bit stickier for a better amount of multi-use before having to be replaced. Other than that, great product!

If you are looking for a good TENS unit at a very affordable price, I would recommend this. I bought one and I have had it for about 3 weeks now and I love it. Works well, easy to use and really does the job it is supposed to do. I like the fact that you can just plug it in to recharge so no need to fool with batteries. The electrodes are easy to attach, and the settings are easy to navigate and use. Mine was fully charged when I got it, and I have used it quite a bit and still have not had to recharge it yet. I got this one to update the one I have had for like 10 years and I am glad I did. Plus, it uses the same electrode pads I had with my old one, so I didn't have to by any new ones. Even so, those are not that expensive, and you can use them over and over again. Good product for the money.

I sit way too much at work, and my back likes to remind me of it—especially that lower left muscle that apparently has a personal vendetta against me. When it gets mad, it really gets mad… sharp, take-your-breath-away kind of pain. I’ve tried it all—muscle relaxers, pain pills, physical therapy. Therapy helps, sure, but my wallet starts crying after a few sessions. So, in a moment of desperation (and a little hope), I started looking into TENS units and stumbled on this TENKER TENS one. At $25, I’ll admit, I was suspicious. I mean, how good can something that costs less than dinner for two really be? But over 10,000 people gave it 4.5 stars, so I thought, “Okay, let’s roll the dice.” Best. Decision. Ever. It showed up fast, I figured out how to use it, and by the end of the first night, the spasms were way down. The next day, I wore it most of the day and felt even better. Now I’m on day three, and my back feels like it just came back from vacation. Seriously—no pain, no stiffness, no regret. The battery life? Unreal. I wish my phone could take notes. If you’re at your wit’s end with back pain and ready to try something that actually works, grab this thing. It’s small, affordable, and kind of miraculous. My cranky back finally shut up—worth every penny.
