Belifu 4 Channels Tens EMS Unit, TENS Unit Muscle Stimulator for Pain Relief, 24 Modes 20 Level Intensity, Electric Pulse Massager with Large Screen, 8 Pads

This produce works very good. It does take some time to get use to the programing to your liking.

I need a replacement for my old one and I’m very pleased with this one. It helps with my muscle soreness. I like the múltiple selection of modes.

It really helped my what they called tennis elbow

It cost almost the same as a visit to the therapist office. I paid close attention to what they were doing after pricing this unit and realized I could have bought a couple of them for myself to use at will. I must say so far so good. Considering it's a 4 channel unit and you need 2 pads per channel, more than 4 pads would be nice.

I've never used a TEMS unit before and have always been a bit skeptical of them, but I decided to give this one a try because of its reasonable price point and the fact that my golfers elbow has been annoying me for a few months now. Fatefully, my thighs were also sore for some reason the day this device arrived.I've only used it a few times so far, but I enjoyed it a lot more than I expected I would and particularly my elbow did seem to feel a little better in the end. I would definitely recommend reading through the manual once before using it because there are a lot of different pulse patterns available (24 in all I think) and the booklet gives examples of what each is good at addressing.The product comes with a few different size patches which adhere to your skin with a sticky gel kind of layer. You can reuse them several times, but I imagine eventually they'll loose their tackiness and need to be replaced. A replacement set of 20 new patches looks to run about $12 currently, which isn't too bad. The patches this uses are the snap on style similar to how you would attach electrical probes in a hospital, as opposed to the DC barrel connection I've seen on some. I think this is a better way to do it, personally. The ones using the barrel connections end up having to have a wire and connecter hanging off of each patch whereas these merely have a small metal snap button, which seems less wasteful and cheaper to produce in the long run.You use two pads per channel and it supports driving up to four simultaneous channels, so you'll utilize at most 8 pads at any one time. Each channel can be programmed to a unique mode, so you can address multiple issues/pains/areas at once. The unit itself has a built in USB-C rechargeable battery which is convenient. You might be covered in wires for your TEMS/EMS pads, but at least you won't be tethered to the wall.You can also program the duration, though it's a single countdown for all of the channels at the same time. It can be set between 10 and 80 minutes in duration, in increments of 10 minutes. I was a little afraid of what it might feel like or how hard it might engage my muscles at first, but was pleased to find it starts at 0 power on all 4 channels and then you adjust them manually one at a time to get the proper response which can be unique depending on the size of muscle and type of stimulation it's using. I don't think I've had to go even as high as half of full power on any channel, even for my larger thigh muscles, to achieve a comfortable stimulation.I do wish it was a little quicker to setup and use as I would be inclined to use it more frequently than I have been, but there's no real getting around that. And it would be real nice and save a lot of setup time if the screen was touch reactive because the way it is now you have to click mode or channel etc to cycle through the modes/channels before landing on the one you want to actually adjust. It reminds me a bit of the old T9 text typing. But, for the price point I can't complain as I'm sure a touchscreen would easily double the price.All in all, I'm really enjoying this device and can see how it could be a little bit addicting and so now I just hope the internal battery and device as whole last several years.

Back in 1991 my first TENS Unit was prescribed by my Orthopedic Surgeon and if I remember correctly it cost my insurance company about $250 and it had only two channels but did provide some welcome relief for me after my lower back fusion surgery. The way my surgeon explained the way it worked to me was the electrical impulses from the TENS unit can reduce the pain signals going to the spinal cord and brain, which may help relieve pain and relax muscles. They may also stimulate the production of endorphins, which are the body's natural painkillers. All I know is that it Works for me!Personally I'm not sure how or why it works and as I've been told by some of my more active friends is that it may work better on some than others. It can be uncomfortable when you first begin using it but it shouldn't be painful. I've never experienced any skin irritations from where the electrode pads are applied but personally I know some people that have.At my age I probably won't use this little device to its' full potential since I will typically only need it to control my lower back pain but it is something I will look into using since it has the Electrical Muscle Stimulation (EMS) technology which is designed to stimulate the muscles for the purposes of strengthening and rehabilitating them. But as I've been told by my friends it is limited to 1-2 times of use per week. This they say will allow time for their muscles to repair and recoup before their next session but as I mentioned I probably won't need this part of it to help me stay in shape since I typically spend much of my time hiking in the mountains of Tennessee...What I really like the most compared to my original TENS unit from 1991 is that this one doesn't eat up 9V batteries, much like I enjoy eating my ice cream deserts, and in place of my old 9V batteries I have the comfort in just being able to plug it in with the supplied USB Type C cable to a charging cube or my PC and letting it recharge so I can begin anew with the pain relief I look so forward too. I will be happy knowing that when my lower back pain kicks into high gear from overexerting this old body of mine I will have the Belifu TENS/EMS Unit ready and waiting to lower or eliminate my oncoming pain level. Just remember that if you've never used a TENS unit to assist you in controlling pain levels anywhere on your body my advice would be to consult with your Doctor first, there are some areas of you body that you wouldn't want to place the electrode pads near...
