Roscoe MedicalTENS Unit and EMS Muscle Stimulator – 16 Electrodes Included, 4-Channel OTC TENS Machine for Back Pain Relief, Lower Back Pain Relief, Neck Pain, Includes Case

Don't waste your $$$ on other gimmicky TENS devices. This is the one which a good chiropractor will use for constant buzzing your muscles.

I had purchased one prior to this one and it was junk. This one is just what I needed. It works great with Batteries, no re charging needed. I haven't had to open all the patches yet, so it definately gives you plenty of them. It helps my ciatic back pain and my feet and ankles. Best Purchase of 2025 by far.

My best friend for my back next neck pain, is just amazing!

I read all the reviews about these massive occasional bursts and thought oh someone’s pads must be loose or they are new to TENS and somehow setting this off. Well, I’ve been using TENS since it was invented, and I have never had one do this. But these do indeed every few minutes give you one increased pulse in all the pads across all channels. It must be a design flaw. However, if it keeps working I will keep it because it is the only unit I can find that uses AA batteries. I just keep it turned a bit low and come to expect those shocks. I like having the four channels, but I must say, setting the thing takes a lot of figuring out; the extensive booklet is just a lot of filler and only 2 pages are useful—but not at all useful enough to explain setting the thing up for a treatment! I ended up just having to play with it until I figured out how it works to set it. Two days of playing with it, I have figured out how to keep each channel on TENS (vs. EMS which I do not like, I wanted TENS and microcurrent in one 4-channel machine but I guess it doesn’t exist) and set the intensity and time. The waveforms, etc., are all just too hard to figure out, so whatever waveform I get to come up first is what I use, SMH. I wish they would explain better. I’m not a physical therapist, just an RN!If you are squeamish about these intermittent shocks, do not buy this unit; they are real, sudden, and, well, shocking!

Great

I use this the day I got it and it worked fine. The second day I used it the ramp up button took off and ramped up all the way to 100 shocking my body causing me to jolt and twist my back and fortunately my husband was here with me and able to pull the pads off since the off button wouldn't work. So the off button was stuck on and the ramp up button and the ramp down button were stuck. Very alarming and scary when it ramps up like that and shocks you so much all of a sudden. Not okay. Sent me into a bit of a shock.

Great unit. Easy to use. Multi-functional.

This is a basic TENS unit at a rather high price point relative to what is supplied. While the unit mostly works as advertised for TENS I think it is stretching the description on the EMS part. In order for me to get any sort of muscular contraction that is noticable, the strength must be set high enough to cause me pain.Also the unit sometimes delivers a jolt when I guess the timing gets off track which, while not dangerous, is off-putting.
