3-in-1 TENS Unit Muscle Stimulator with 30 Modes for Pain Relief

Excellent. Read the booklet so you can select whether you want TENS or EMS. Instructions are easy, I feel it's been very helpful for my low back pain.

So grateful for this TENS unit, it provided back pain relief like nothing else I tried. I’m a disabled veteran and have a service-related back injury that is easily reinjured, and can take me out for several days to several weeks. (For context, I’ve had two natural deliveries and my pain threshold is extremely high.) I’ve used TENS units before at chiropractor and physical therapist offices, but they always just hurt while in use. I really appreciate all of the settings on this unit, and find it incredibly soothing for different pain locations. It’s been helpful for pain that is numb, sharp, radiating, etc. The pads are very sticky, stay in place well, and don’t hurt to remove. I do find that sometimes the wire connectors pop off if I adjust a bit, but that’s mostly a me issue. The battery life has been long so far as well! Highly recommend!

Easy to use, provides great relief of back muscle pain. Battery lasts very long!

I’m really happy with the AVCOO 3-in-1 TENS Muscle Stimulator. It’s easy to use, comfortable, and convenient to have at home when I need some extra relief and relaxation. The different modes and intensity levels make it easy to adjust to my preference. I also like that it’s compact and portable, so it’s easy to take with me. Overall, it’s a practical and useful device for everyday use, and I’m pleased with my purchase.

Amazed how great this is. Long battery life and strong pulses. Super easy to operate
