  • Helpful for Shoulder Pain
Color: Black
Excellent little unit! I slept on my shoulder wrong and have been experiencing awful neck pain. The TENS Unit arrived quickly and has definitely lessened the pain already. It is small and easy to use, I recommend this item.

  • One of the best for all day use & battery
Color: Black
Guys this is just awesome. It is effective on relaxing your muscles. Also works on swollen areas as electricity helps with it. It is very powerful I haven't used it full power. Wife and me can't tolerate it. Looks and has been holding strong since I bought it. Size is very compact you can use it to work easily with battery lasting all day, keep in mind we don't use it full power. This may affect battery life. Four starts because it is not super easy to select modes. Besides that this is awesome. ... show more

  • Tiny, powerful, and an insane value
Color: Black
For the price, this is incredible. I'm pretty tolerant of pain, but this device has 24 different settings and you can change the power of each one from the lightest of tingle to so powerful you'll be wincing. I've had it zapping me for over an hour today and it's still claiming it's at full bars of charge. The pads are very sticky, and if you dab a damp finger on them it'll apparently make the pads last a lot longer. You can put in two sets of leads as well and it even comes with one with 4 attachments. I've only used a single double pad system so far, but it's great. As for if it will help you with whatever you're dealing with, who knows! But at this price if you're reading this, why not try? The main part is tiny, about the size of a credit card and under half an inch thick. No idea how this tiny thing can zap you like it does. My back pain definitely feels less severe when I use it and after as well. Not sure if that's because the constant zapping kind of gives you that numb feeling, or if it's actually helping. Regardless, it's less severe! ... show more

  • Amazing!
Color: Black
This thing works! I only used it twice and it helped with my shoulder pain. I can only imagine what it can do if used on a more consistent basis. Get this if you have soreness or any type of pain

  • Great affordable product
Color: Black
Works great, battery lasted quite awhile before recharge was needed. I only wish it had a mode that was a longer constant electrical stimulation for personal preference.

  • Uncomfortable Stinging Pulses
Color: Blue
The unit itself is fine and the battery lasts a long time but the pulse it delivers stings my skin and is uncomfortable at any power level or mode. Not a deep stimulation but a surface level sting. I've tried several different pads but it hasn't helped.
