AUVON 4 Outputs TENS Unit EMS Muscle Stimulator Machine for Pain Relief Therapy with 24 Modes Electric Pulse Massager, 2" and 2"x4" Electrodes Pads, BlackCarbonfree Certified

I’m not going pretend to understand the science behind this product, but I’ve used it for a little while, and I’m comfortable speaking as to my personal experiences.It looks and works as you would expect. The unit is the size of a deck of cards, and it comes with four sets of wires, and some electrodes. The wires connect the electrodes to the unit. The electrodes stick on to your skin in a way that you have possibly experienced in a hospital or therapeutic setting. Just put a few drops of water on them and they adhere to skin nicely.Once you are hooked up, you have your choice of 24 settings for the type of treatment that you want, and then within that type, you can choose the strength of the treatment that you want. As other reviewers have mentioned, for being a small rechargeable unit, the higher settings are surprisingly powerful.So, what exactly are these treatments, and what do they do? How does it feel? The treatments work by transmitting an electrical current into your skin. The electricity stored in the unit travels through the wires into the electrodes, and into your skin. So, what’s good about that? The electricity doesn’t just go skin deep. It goes into the underlying muscles, and that’s where the magic happens.The electrical stimulation causes your muscles to have some activity. It can be just a tiny tingle, or a much stronger effect. I didn’t really entire believe that something small and rechargeable could have a big effect. However, at medium settings, the effect can be strong enough to make the muscles below the electrodes twitch, or even clench and contract.So, what’s that good for? Recently, I had one of those nasty bugs that caused me to cough so hard that I had sore muscles in my back, sides, and abdomen. I put the electrodes onto the affected areas and used a low setting. The little tingle that the electricity put into the sore muscles was very soothing, just the thing I like that I needed.It can handle other issues as well, such as keeping muscles from atrophy if they can’t be normally used. It can range from what feels like a gentle massage all the way to what feels like actually working the muscles.I ran it by my physical therapist, just to be safe, and she gave me the green light.I don’t want to promise you’ll have some sort of miracle, but I can honestly say that I am quite happy with my results so far. Just based on what I’ve experienced so far, if I tried this out at a friend’s house, I would have easily believed that this product could sell for $250-$350. Naturally, it feels to me like a bargain. I’m even willing to say that if I wasn’t one who steers clear of other people’s health (because I’m not a doctor), I’d recommend this to friends and family. I’m even considering breaking my own rule and giving one or two as a gift.So yeah, that all sounds too good to be true to me, and I’m the one who wrote it!TL; DR - I like this little gadget a lot!

My old, other brand TENS/EMS unit needed to be replaced & I was excited to find a dual channel unit that can run 2 modes independently! I received this yesterday and have used it for 2-60 minute sessions. It was fully charged out of the box. The user manual is easy to understand. It actually feels like holding a cell phone. I love that it has a locking feature...no more accidental cancelling the session. One thing the manual doesn’t tell you is you can long press the mode button to more quickly go to each master program mode, then short press to choose the sub-mode...makes it a little quicker to move through the modes. The lowest intensity is very low...which is good. Some units start out too high, which can be painful depending on the need.What I like:* Lock feature* 2 channels, each with 2 ports (4 ports total)* Each channel can run a different mode independent of the other.* Each channel can be a different intensity* Small enough to fit in your back pocket* Good range of low to high intensities* USB rechargeable...no more batteries!* Good quality pads in 2 sizes.What I would update:* Include a clip...sometimes you don’t have a pocket* Wish you could move backwards through the modes* Design it so the lead wire pushes flush to the unit. Right now there’s a gap and I’m afraid I’ll push too hard and dislodge the inner workings. (Happened before on a different unit.)I’ve only had it 2 days, so I’ll update if anything changes, but I'm happy with it's performance and the pain relief I receive!

Great unit overall. Well worth the price. Ease of use covered well in other reviews. Only awkward thing is it has an old USB plug. It looks like Auvon finally upgraded to standard USB-C in 2023 or so for their tens units. But the long use battery makes this still a good unit.

Got for post ACL repair surgery and it works really well! Great 2 in 1 unit.

Easy to use and quite effective for an OTC quality TENS unit.

Had broken my hip at 30yrs old, no rhyme or reason, had lived with pain for said 10 years since surgery. Did PT, taught myself yoga ( now being certified) while yoga did help both physically and mentally, there was still some pain to deal with, mostly deep muscle and nerve issues. I came across my first TENS unit a couple years ago and started using it, it helped so much! then it broke, got this beauty and let me tell you I am so glad I upgraded. Being able to have 4 outputs, (which means 8 different areas to cover) helps significantly! When my hip/leg hurts it's not always because of pain in the leg, it starts in the lower back, so being able to have both back and leg covered helps manage the pain when needed. My first unit worked great for a few days, but one output seemed to stop working all together, I contacted the company and they got in touch with me so fast! They tried to troubleshoot my issue and it ended up needing to be replaced, which came within days! I am so thankful for my Auvon unit and recommend it for anyone who lives with chronic pain. There's many different settings, ( which my old unit didn't do) So I can choose from TENS to MUSCLE stimulator, and what a difference! I like how you can change each separate one to a different setting, if I had half the pads on my right side and the other on my left where the pain was different you can set it differently. There's 24 modes to choose from and they are all great! I would say always start slow, find that comfortable setting and work up from there when needed. It does seem to need to be charged a lot though, that's kind of a downside for me, but it still runs long enough to get the job done!Great unit, and an amazing company!

My husband really likes this product for shoulder pain, neck pain and back pain. It seems to work as he feels much better right after using it. They give you instrux on how to place the pads and what not to do. Easy to work. Would recommend
