AVCOO 3-in-1 TENS Unit Muscle Stimulator with 30 Modes, 40 Intensities TENS Machine for Gradual Back Pain Relief Therapy, Rechargeable EMS Unit Massager with 12 TENS Electrode Pads, a Storage Bag

I have been in PT for nearly two years, and the thing I consistently get the most out of is EMS. I'm trying to get to where I can discontinue PT (with my team's agreement), but I don't want to give up stim, so I bought this to try a home option. I've had another in earlier years and it did not do much, but I am surprisingly thrilled with this unit. For the price point, it actually works very well. I have been pleasantly surprised to find it does a better job than I had expecting for a small, "civilian" unit. It's very simple to use, it's compact, the pads are of good quality and it's easy to get replacements for them, and they stick extremely well for a handful of uses. I think I've gotten around 8-10 uses per pad. I use this little machine daily and I do feel a difference, as gauged by less pain and better sleep. Great product for a reasonable price.

I bought this AVCoo TENS unit hoping for some relief and ended up wondering why I didn’t get one sooner, because this little device absolutely gets the job done. The pads stick really well (no peeling off mid-session), the settings are easy to understand, and the different modes actually feel different instead of all being the same buzz with fancy names. It gives a strong, consistent massage that feels like tiny professionals going to work on sore muscles, and the intensity levels go high enough to mean business without feeling out of control. I’ve used it on my back, shoulders, and legs, and every time it delivers that “ahhh” feeling that makes you sit there longer than planned. Battery life is solid, the screen is clear, and switching modes is simple even if you’re half asleep relaxing. Fair warning though—start low unless you enjoy being politely reminded that electricity is not a joke. Overall, it’s a great massager for pain relief and muscle relaxation, works exactly as advertised, and for the price it feels like having a mini massage therapist that doesn’t talk and never asks for a tip.

Works exceptionally well really loosened up tight back muscle muscles and relieved pain. Battery life is exceptional. I appreciate the fact that it’s small enough to fit in my travel bag. Easy to use and straightforward. I appreciate the multifunction of tens, EMS, relax.

I bought this muscle stimulator to help relax my muscles after intense training days and also heavy days at work, it’s working very well the patches provided are sticky and reusable, I like the design is very small and compact and you can get a lot of hours of therapy with one charge on the unit is easy to use, the only thing I would improve will be add a belt clip or a clip that can be attached to your clothes don’t have any, but over all I give it 5 stars, solid and good quality product.

There are 3 Modes for each part: TENS, EMS, and RELAX. There are 40 levels of intensity. CH1 or CH2 can be used by itself. The same Mode can only be used when using both CH1 and CH2. The display screen blinks when remaining 1 minute is reached and the device turns OFF when time is complete. I think it is best if the switch is turned Off before storing.
