More Product Than I Expected for the Price and Size
This unit is more than I expected!! I purchased this to replace a model that I already owned of a different brand. The older unit was a wheel dial and was showing wear and tear. I was interested in this unit because it offered TENS, EMS, and Massage. I have used all three features. This unit is easy to use, has a bright LED screen, and the two independent leads is great for targeting areas like the neck/shoulder and wrists for neuropathy that I have been experiencing. My mother was suffering from neck pain and shoulder tightness after a hospital stay recently and after an anti-inflammatory, and an RX pain pill, she was still in moderate pain. I placed some larger pads that I purchased on her upper shoulders and smaller round pads un the base of her neck, chose the Massage feature on the Combo setting and within minutes her pain was easing off and 15 mins later she was asleep. I also love the fact that you can set the time up to 90 minutes. The unit is smaller than expected and the leads have a long cord. The unit can be paused, and also locked so you don’t have to worry about the settings changing, even in a pocket. I purchased a 48-piece replacement pad of another brand and they work perfectly. For what I received, I would have thought it would have costed much more—excellent value for the price. Easily wipes off and comes with a small pouch for storing. I would highly recommend this unit for anyone looking for a TENS/EMS/Massage unit.

We LOVE this little Tens Unit! Gentle Yet Powerful if you need it!
I had one of these like 20 years ago that worked fairly well, but it broke a long time ago. I bought another one off of amazon maybe 7 yrs ago and it was so painful to use, it just didn't work right. I was reluctant to try another, but knowing I used to have a good one and my chiropractor has a good one, I knew it was a matter of trying them and reading reviews to find a good one. THIS IS IT!!! I'm in LOVE with the way this one works and the features that it offers!!! I have mostly only used it on #1 because it's good enough to stimulate without over doing it. I tried bumping it up to 4 once, but it seemed to feel better on #1 or #2, so I went back down. It works well, offers pain relief, and I believe this unit is a Wonderful Value for the money when it makes me feel better!! I love the different settings, and what's amazing to me is that it actually feels just like the descriptions... it's like there's a massage therapist actually doing those things!! I don't know how they program electric-stim with that type of feeing, but it's just WONDERFUL!! If you want a good machine at a decent price, this is it! I can't speak for longevity yet; but so far, it's held the charge and I've used it several times on that charge, so it's good enough for me! I hope it keeps working for a long, LONG time into the future!!

Massage Muscle Stimulator
I had no trouble putting it together; the box came with a full twelve electrode pads, and the directions were easy to understand, so I was able to get started without any misunderstanding. It is my opinion that the dual-channel capability is very helpful since it enables me to concurrently target two separate locations, such as my shoulders and my lower back. I am able to tailor each session to my particular requirements on any given day thanks to the massage and muscle stimulation alternatives that are available to me. For instance, I utilize the Electronic Muscle Stimulation (EMS) mode to assist in the rehabilitation of my muscles after a strenuous exercise. On days when I am experiencing general pain, the massage mode offers me comfortable respite. My ability to fine-tune the experience to what is comfortable for me is made possible by the fact that the intensity levels are extremely customizable. On the other hand, I have had negative experiences in the past with devices that are comparable to this one, where the battery life was disappointing. However, the fact that this device can be recharged came as a great surprise to me. It has a good capacity for holding a charge, and it can be used for a number of sessions before it has to be recharged. This is not only handy, but it also saves me money since I don't have to continually purchase batteries.

Decent
It is a good TENS machine. The massage works the best tbh. It is kind of temperamental, I've had it turn one or both channels off randomly. Or if you are trying to find the right setting, it will start, stop and reset itself. It's not all the time but still could do without that.

Great for pain relief
I’ve tried a few TENS units before, but this one really stands out. The 4-in-1 DIY design with dual channels gives me full control over how I manage muscle tension and pain. Being able to customize the settings and switch between modes so easily has made a huge difference in my recovery routine. The advanced electrode pads are super comfortable and skin-friendly, and I love that they’re reusable. They stay in place well and deliver consistent relief without irritation. The device’s sleek, user-friendly interface makes operation completely hassle-free—even for someone new to EMS units. Another big plus is the built-in rechargeable battery. No more scrambling for replacements! It lasts a long time on a single charge, which is perfect for regular use. The complete kit has everything I needed right out of the box—TENS unit, wires, pads, and even a pouch for storage. It’s clearly designed with convenience in mind. Not really sure or convinced yet it’s worth the extra cost of some of the other units.

I've had back pain for a while which prevents me from doing much physical movements to strengthen my back muscles. This device has allowed me to stretch my muscles which has made a difference in my back pain quite a bit. It has a lot of different modes so you can select the one you really like and what suits you. Its better than the Dr. Hos product I used to use.
