TENS Unit Muscle Stimulator - Non-Invasive EMS Therapy Machine for Neck, Shoulder & Back Pain Relief, Sciatica, Arthritis - Safe & Portable with 12 Modes & 20 Intensity Levels

I've been using this device for a couple of months now and it has really helped with my lower back pain due to muscle spasms. It works much better and is much more versatile than the TENS units I have purchased in the past at drug stores, and it's not that much more expensive, so it's definitely been worth the extra cost. I really like the many stimulation mode choices (although there are only two or three that work best for my pain and that I use regularly), and I like the fact that you can set both the stimulation time and the force. It's also great to have electrical muscle stimulation modes as well as TENS modes. EMS is like getting a back massage and has been really helpful for me. The package comes with three different size electrode pads--I use the two large ones for my back and my daughter has used the two medium ones on her abdomen to treat menstrual pain (with TENS) and it worked for that, too. So far, I haven't used both channels (4 electrode pads) at once, but you could do that too if you needed to cover a larger area. Other things I like about this system: the hand-held controller lets you actually see what you're doing when you set the mode and force (with the other TENS units I've had, the controller part was attached to the electrode pad so I had to reach back blindly to adjust the force), and the rechargeable battery is nice as well, although once I tried to use the device and it didn't work because the battery was dead, so you have to remember to plug it in and recharge it. I just plug it in for several hours after each use now. Since I've only had it for a short time, I can't speak to durability, but from what I've experienced thus far, I give it five stars.

I had total knee replacement 3 weeks ago and had asked my PT about a home EMS unit. He directed me to Amazon and said to pick one that I liked. I reviewed a dozen or so TENS/EMS units and decided that I definitely wanted on that had a rechargeable battery and that was my main requirement going in. I had concerns about the strength of the stimulation and the placement of the pads; but I was really leary of the wide variance in price. Many times, "you get what you pay for". This unit is on the low end of the price range, but it performs wonderfully. There are 12 different settings to pick from that offer different sensations. I have picked out my favorite two for my regular treatment and I am experimenting on different muscles, as I notice soreness, and different settings as I get used to the unit. I could not be happier with this system. It is straight forward and easy to use, even for my wife who is technology challenged, and uses the lowest possible intensity level possible. At therapy, I have them turn the intensity all the way up and then wish there were more. With this TENS unit, I keep it under half intensity and can mix and match the stimulation. The only recurring complaint I noticed in the reviews is that amount of time allowed for non-use of the screen is too short. The back light goes dark way too soon. These complaints are absolutely valid. However, touching the screen brings it back pretty easily, with practice. I don't normally give reviews, but I do highly recommend this product.

Very useful, eliminates fatigue after use.

First of all, I will just let you know: I call this my zapper.Pros:-Many options for zapping (muscle stimulation) patterns-Plenty of power (this is also a negative because it is often too intense for my forearms— see more below)-Three pad sizes-Easy to use-Comes with a cheat sheet for where to put pads to work on specific issuesCons:-Pads don’t stay sticky for more than a few uses (definitely have to be strict about using rubbing alcohol on your skin before applying the pads, as it doesn’t take much to lose the pads’ stickiness)-Power/intensity starts too strong (as mentioned above, it’s painful if I turn it up much past the very lowest level; depending how close together you place the pads, even the lowest setting is too much and I can’t imagine going up to 20 except maaaaybe if you put one pad on your lower back and one on your hamstring, like an example in the manual; for reference, the one they use on me at PT is on level 8 and placed on the same forearm spots as I use with this one at home)-Zapping pattern isn’t synced if you use both sets at the same time, unlike the pro one at PT (with this, you start each side separately and even if you time it to start the second set when the pattern gets back around the the beginning on the first set, they aren’t going at the same speed for some reason, so it’s kind of all over the place— the real issue with that is that when one side is mid-crescendo the other side starts its crescendo and sucks power from the first one; not the end of the world, but definitely annoying)Overall, I’m happy with it.

Just using it right now on husband. He has neck and shoulder pain. I used an old tens unit on him yesterday but it had seen it better days. This one is a upgrade and is so perfect. It works well...it might seem difficult to operate but once you unbox it and read directions and hook up leads it is just a matter of referring to instructions to see what feels best....always start with lowest settings...this is a GREAT handheld device. Will be getting much use out of this.

excellent product
