TENS 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

Works like the unit on a cart in the PT office. My insurance would not pay for me to rent one, so my doc recommended that I buy this one on Amazon. It works great and is pretty easy to use.

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.

Very well packaged. Great working compact device. Carry case makes storage and travel comfortable and easy

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!

Just got into using TENS. Already own the two-channel version, but like that this one uses AA batteries and that the amplitude is digitally controlled. Good value with the extra TENS pads.

This is the second one I've purchased and it performs as to specifications

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.

I had a rotator cuff surgery / repair a few months ago and physical therapy was using a TENS unit as part of my therapy / recovery. I loved it, but didn't want something quite that fancy. I decided to try the Roscoe TENS/EMS 4-Channel and haven't looked back. It does everything their fancy machine did and does it well. I still use it from time to time to massage and help with flow in the calves after a 14 hour shift. I can't complain about a single thing with this machine, even the supplied pads lasted for months. Great machine and well worth the price.
