The item shipped quickly. Works great! I was able to use on both my shoulder and back at the same time. It’s compact enough that I can keep in my back pocket, have the pad attached under my clothes and use during work to relieve pain that I may be experiencing. The unit charges quickly and the battery life is amazing. The unit powers on easily with a slide button and charges with a usb cord which is included in the packaging.

I love this. It’s tiny in size, easy to handle, battery life is good, it’s effective, and functional. The pads stick good and it’s definitely worth the money. Plus it comes in my favorite color.

This TENS unit is amazing! Both my husband and I have dealt with back pain for years, and this device really helps. It’s especially effective for pulled muscles or when you just need to take the edge off the pain. Easy to use, with strong but adjustable settings. Definitely a great addition to our home pain relief routine!”

I love that you can charge this thing really anywhere so you never had to worry about batteries. I have a bad back and this has been a life saver, its more powerful then I expected. I will say if you plan on using this on a daily or even more then once a week you will need to grab some extra pads as the stickiness doesn't last long. I really also like that it has quite a few options and not just one setting... Its pretty easy to use and I think its worth the money 100%

This is a fabulous little machine. I have a bad back that I have chiropractic care for. I use this machine in between visits and whenever discomfort requiresattention. After much experimenting I am comfortable using this. Follow booklet directions and start on low settings. Machine is powerful enough to give a good jolt so again start low and see what is good for you. I have purchased twice because I gave first unit away. Highly recommend this very helpful or pain device.

This is a great unit. It keeps a charge for a long time after multiple uses. The quality is excellent for the low cost and I appreciate its small convenient size.

What can I say, I’m a skeptic. For the price point - which is incredible - I didn’t have a whole lotta faith that this would be a solid product and that it could tackle my oftentimes debilitating back (specifically Beck and shoulder) pain. But was I wrong on all accounts. This little guy packs a punch and it put a beating on my shoulder blade muscle knot. Highly recommend this product at either price point (I got mine on sale, worth every penny), but I’d gladly pay the original sticker price too. It’s as good a product as the one my chiropractor has in his office.

Update: Unfortunately one of the connections (2 of affecting 2 of 4 pads) stopped working. The unit still functions but at about 50% capacity. I used it 4 times before it malfunctioned.Why did you pick this product vs others?:Works very well, compact and easy to use.Battery life:Great battery life!
