Great little Tens unit, holds charge for several uses and the extra pads are a bonus. I am able to go for a 1.5hour long walk with the unit continuously working my back and the clip holding securely on my pants/shorts. Only thing I don't like is the wires, but most wireless tens unit can't match this one's tense strength. It also surpasses those in that I can adjust frequency and pulse width and set a timer. I would recommend this tens unit to anyone have muscle pain issues.

AWESOME machine! Easy to use and understand! Works better than expected!

My wife and I use this daily it works great has helped her lower back problem and my bad left shoulder. I use all of the settings on it they all work great it's very easy to use I couldn't be happier with the product.

Working good for my pain relief!!

These worked well for us; easy to use, long lasting battery after initial charge. In my case my lower back went out; so much so it was difficult to walk, condition persisted over a week. Tried all the normal treatments. Epsom salt baths, pain creams, but back stayed painful. Found this device, read the reviews, and ordered it. Actually read the manual before use, it is really easy to use. I applied the large pads to either side of lower back, ran it at level 21 in normal mode. Repeated same after warm shower for 2 days in a row, on the 3rd day back pain completely gone, and has not returned. Wife suffers from leg pain, used smaller pads, applied to area of pain at level 22 for 15 minutes. Afterwards no pain. in that area. It comes in a nice plastic box with everything you require, easy for us to take on trips, and use anywhere.

Works great! It's pretty powerful and holds a charge for a couple weeks. I've been using the sticky pads it came with and they're still holding on really good! I really like the different intensity settings. The fact that it's compact allows me to put it in my pocket and do whatever. All in all it's a great buy.

I was dealing with a quite uncomfortable back tweak that made sitting and even lying and sleeping pretty difficult. Using this allowed me to make it through the day with less distraction from pain and less discomfort. I love that it's rechargeable and has different modes. Very portable and relatively light weight. Make sure to look up how to use these. There are two main ways to use them - Gate Control (superficial immediate pain reduction) and Endorphin Release (longer, deeper pain relief accomplished over time) Here's the breakdown: General Goal: Pain Relief (Gate Control Theory) Frequency (Rate): 80–120 Hz Pulse Width (Duration): 50–150 µs (microseconds) This high-frequency, low-intensity mode provides immediate pain relief, which lasts only while the unit is on or shortly after. Goal: Deeper Pain Relief via Endorphin Release Frequency (Rate): 2–10 Hz Pulse Width (Duration): 150–250 µs This low-frequency, higher-intensity setting stimulates the body to release endorphins and may provide longer-lasting pain relief, though the effects come on more slowly. You can alternate between both modes throughout the day or based on your activity level: During the day when you need pain relief to function: use high-frequency (80–120 Hz) with lower pulse width (100–150 µs). At rest or in the evening: switch to low-frequency (2–10 Hz) with longer pulse width (150–250 µs) for more prolonged relief. --- ChatGPT is also surprisingly effective at helping you decide where to place the pads and what mode- so I recommend consulting it for your specific situation.

Dear team The device worked well without any problems until today. During normal use, the (+) button suddenly stopped working and no longer responds, while the rest of the device still works. I would like to contact the seller to arrange sending the device for inspection and repair under warranty, if applicable.
