AVCOO 3-in-1 TENS Unit Muscle Stimulator, EMS Massager Machine with 24 Modes & 40 Levels for Shoulder, Back, Neck, Sciatica Pain Relief, Portable-Size Electronic Pulse Massager with 12 Pads, EVA Case

I am an electrical enigneer that mostly does firmware and software development. I also do board design and productization as well as data center AI development. I am often hunched over my workbench or spending hours and hours at my desk editing code or my designs. I get terrible back pain between my shoulder blades and just below my neck. I have CKD stage 2-3A, which means I can't take NSAIDs else my kidneys will get destroyed. I want o avoid dialysis and death until I am ready to shake this mortal coil off. My nephrologists recommended my PCP to prescribe Tramadol. Which to me, is like a placebo. I feel no effect from it at all (yet they consider it a narcotic - uhm no). Was researching pain relief that is actually effective for CKD patients and its basically narcotics, nerve blocks, or TENS/EMS. I spend some time searching through all the various manufacturers and settled on this one. I am extremely happy with the performance. It ie extremely easy to use. It holds a charge for hours and hours of use. The high quality hard case is very nice. It has som many different patterns of nerve/muscle stimulation. It doesn't necessarily remove the pain, but it does make it so it isn't so terrible. The different pulse and strengths allow me to really dial in the pain relief. This is also an EMS unit. Meaning it can also be used to build muscle and prevent atrophy. It works very well. It is so powerful, I can't even put it to the highest strength. Well worth the money. It is almost hard to believe you can get this quality for the price. I can remember years ago when I wsa in the Marines I had a muscle stimulator to help build my abs. That thing was like 500 bucks - 20 years ago. This one is much better than that for less than 10th the cost and 1/4 the size. This is so small its hard to believe. I also picked up some extra pads, even though the pads continue to work forever as long as you put them back on their wrapper or on the included plastic card. I would definitely recommend and would buy again.

I absolutely love the AVCOO Dual Channel TENS Unit Muscle Stimulator, 3-in-1—it’s hands-down the best one we’ve owned out of three different TENS units we’ve tried over the years. This thing is seriously powerful, with adjustable intensity levels that let you fine-tune the sensation, from a gentle pulse for relaxation to a deep, therapeutic jolt for muscle relief. The dual channels are a lifesaver, letting me target multiple areas simultaneously without any fuss. The battery life is outstanding—I’ve used it for multiple 30-minute sessions daily, and it easily lasts a full week before needing a recharge. Setup is a breeze, and the 3-in-1 functionality (TENS, EMS, and massage modes) covers all my pain management and recovery needs. Compared to the other TENS units we own, this one blows them out of the water in terms of power, versatility, and reliability. If you’re looking for a top-notch muscle stimulator that delivers results without compromising on convenience, this is it. Highly recommend!

Bought this as a present for my husband and he loves it. Easy to use, the pads are perfect and sticky. The design is small so it can be handled with just one hand. It feels well made and durable. My husband said he has felt the relief in his heck and back pain since using it.

So far I love it! I do feel like the vibration has gotten alittle weaker after 5 weeks but I can still turn it up to desired level. Pads works well but occasionally snap off if I'm moving around. Battery is still fully charged. Overall love this device!

Oh. My. HECK! 10 stars. Where has this been all my life? I have restless leg a LOT and find it very hard to relax and sleep. I use this for just 5 minutes on the troubled areas and the spasms are gone and the muscles are relaxed. WOW! I did not think it would help so quickly! The pads are removable and reusable. It takes a bit of work to take them off, but do NOT discard the plastic cover when you remove them from the sticky part. And yes, you must stick the pads to your skin in order for it to work. (I tried, haha) The directions are super easy to follow to get started using it pretty quickly. I love that it is rechargeable! The only thing I'm bummed about is the fact that the manuals don't go into details about the different settings and what they would be for. Try them all out. Each setting has multiple sub settings in it for different types of stimuli. Then you can adjust the intensity. So far, I've only been able to stand it at a 6 on one level but 5 on most, and one, I don't go past 4. So, there is a LOT more that you can do. This is such a small device but packs a punch and is so wonderful. I'm so excited to try it out on other troubled body areas that get so fatigued. This is so compact and easy to carry with you. It is a wonderful device for muscle care! Oh, yeah, and it also uses USB C to charge.

I've never had a TENS unit before so I have nothing to compare it to, but it seems to work really well. I had sciatica pain so decided to buy this when my chiropractor recommended buying one. The first time I used it, I didn't know any better, I turned that sucker up to max power and it had my entire lower right side locked up, I imagine its what being tased feels like, I turned it to a shiatsu setting and my entire right buttcheek was twerking. It had me in tears from pain and laughing. I eventually got the hang of after reading the instructions (which I probably should have done from the beginning) and it works really well. Holds charge, sticky enough to stay, and really helped with the pain temporarily.
