Review: Convenient, reusable, and effective - This is my first tens unit and wow do I love it. I got this specifically to avoid cords and going through single use pads. Out of the about 8x ive used it ive only had to wash the gel pad twice. The remote has a screen which I love and the intensity settings are amazing. This is insanely convenient for using at work and holds up to my walking, bending, and stooping. The charge lasted quite a bit and ive only had to recharge once. This is one of my favorite pain relief methods after years of pills and patches.
Review: Great relief - excellent product

## Questions & Answers

**Q: What is TENS Therapy?**
A: TENS Therapy is a transcutaneous electrical nerve stimulator intended for the symptomatic relief of chronic intractable pain and the temporary pain relief associated with sore, aching muscles in the arm, shoulder, neck, back, waist, abdomen, and leg.

**Q: How does PainX TENS Therapy relieve pain?**
A: PainX uses exclusive Limited Total Energy (LTE) waveform technology incorporating the longest pulse duration in its class, and delivers current into deeper regions for fast pain relief.

**Q: How does it work?**
A: TENS therapy relieves pain by blocking pain impulses in underlying nerves with low-voltage electric current delivered via electrodes. These gentle electrical pulses also increase the production of the body’s natural painkillers.

**Q: What does TENS feel like?**
A: Typically patients feel a sensation of tingling, tapping, buzzing or muscle twitching. Patients may habituate to the sensation over time.

**Q: How to Get Started?**
A: Your PainX TENS is equipped with 6 therapy modes. We recommend that you initially experiment using all modes. The mode or a combination of modes with the most feeling and comfort is the best one to use for your desired therapy session.

excellent product

### ⭐ Works sometimes.
*by K***H on December 17, 2025*

The remote doesn’t work at all. It blinks but does nothing to adjust the device. Only one side of the device works and it’s inconsistent. I’ve gone through the troubleshooting and it hasn’t helped. This may end up getting returned or tossed.
