Customers find the TENS unit effective for pain relief, with one reporting it worked wonders for a lower herniated disc.

★★★★★

Very helpful and easy to use

ChewbduOctober 19, 2025

I recently had surgery that involved a lot of sitting and laying during recovery. This led to body stiffness especially in my neck. I went to the chiropractor and he commented on all the knots I had in my back and especially my neck. He would adjust everything and before I got back out to my truck I could feel it all tightening again. I tried heat, cold, pain relievers, laying down, walking around, and hot baths. I got my back to loosen up but not my neck to my shoulders. My daughter and Chiro both suggested a TENS so it was certainly worth a try. It took a couple of weeks but my neck loosened up. This is a great little unit that comes with everything and is easy to use. It has different settings for mode, timing, and intensity. Wish I’d have bought one years ago! Read more

Great product for lower back pain

Robert CarrollDecember 25, 2025

With a hot heating pad, this product worked wonders on my lower herniated disc. Pain gradually, but quickly, went away the next 2 days. If I did not have this product I probably would have been in pain for 2 weeks. Great product! Read more

Comparable to much more expensive units

Melody WallaceSeptember 19, 2025

My last tens was an oxiline pro, so it had a touchscreen and all sorts of fancy features, plus it put me out $100. I genuinely like this unit better. I really didn’t think I would. I felt like I was settling because I broke my oxiline dropping it on the floor one too many times the other day and didn’t have the money to immediately replace it, but now I don’t want to. The physical buttons are honestly so much better than a touchscreen for a tens unit, especially for when I’m at work and keeping it in my pocket. The pads that came with it are super sticky and don’t leave me with any skin irritation. The battery lasts all day. There are tons of great settings and the pain relief is just as good, if not better than what I got from my more expensive tens. I think this unit is a phenomenal quality for the price and I couldn’t recommend enough. I am not kidding when I say I almost regret buying a more expensive one to begin with. Read more

Very simple. Very powerful.

James M.November 23, 2025

This little unit is extremely powerful. I have been suffering from bulging discs and paresthesia for 7 months now. My physical therapist loaned me an extremely expensive and complicated unit that has been wonderful, but because I have to return it to him, I took a chance on this one. Although it lacks many of the features that the professional unit has, it hits MUCH HARDER than the professional unit. Honestly, although it lacks the sophistication and features of the professional unit, it is much more effective simply due to the unit's strength. If you are looking for a basic unit then this really is the one for you! Read more

Works great!

Rachel KroegerJanuary 3, 2026

Works great to release tension in my neck and helps with my migraines. The battery life is long lasting. My only complaint is it doesn’t always stick well. Read more

Versatile and effective! Great buy!

MayaNovember 29, 2025

Update: I got the unit to work and although I got it for muscle recovery, I found it to be SUPER helpful and enjoyable for lower back and pelvic aching. Feels like a little escape/massage that I can easily enjoy while working from home or relaxing in the bed before going to sleep for the night. It really is a great product and $23 well spent!
