NURSAL Dual Channel 3-in-1 TENS Unit Muscle Stimulator, EVA Travel Case Electronic Pulse Massager, 24 Modes TENS EMS Machine, Muscle Massager for Shoulder, Neck, Sciatica and Back Pain Relief Therapy

We bought this electric stim machine from Amazon because we are in our 70's and both have sore backs and necks. It's called a TENS MACHINE .We worked in Chiropractic office for over 21 years and although it's smaller than the ones the Dr.'s use. it gets the job done. We use it all the time now that we are retired. Make sure to read all the instructions before use. When the pads no longer stick, you can reorder just the pads from Amazon.

Bought a a gift for a close family member with back strain. I highly recommend trying a tens unit if you often have muscle issues and strain.

Sirve para lo que se supone que sirve, lo que si ko es de muy buena calidad son las almohadillas, enseguida dejan de adherirse a la piel, incluso compré otras para reemplazarlas y lo mismo.

I had one of these years ago and when it finally stopped working- I went online to find another one. This one has all the bells and whistles! Love it and really helps with easing pain. highly recommend!

It’s better than a physician and the best part is that you can use it at home and anytime you want!

I used this device for several hours daily however, the unit only lasted 5 months before the intensity control buttons (+ and -) ceased to function on both A and B controls. I gave 3 stars as the unit performed pretty well for its initial cost during its short life but it took some time to get used to all the "modes". Actually, it probably has too many modes. I'm not sure that I will purchase this unit again but I will be purchasing another TENS device. I plan to contact NURSAL to see if they would be willing to replace my device. If they do, I will post an update.

Great product. Battery life is very good. Easy to use and gel pads are durable.

Received product, works great, love this product ,will use it every day, Mike.
