Customers say
Customers find the TENS unit effective for pain relief, particularly for back and knee issues, and appreciate its ease of use, especially for work. The product offers good value as a replacement for older units, though battery life and durability receive mixed feedback – while some report it lasts quite a bit, others mention the battery won’t hold a charge and units don’t last long. The remote control and stickiness features also receive mixed reviews.

Matt Alick –
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.
Very very good product –
Soterix Medical PainX TENS -Excellent
Why did you pick this product vs others?:From the reviews and affordability. I had a problem with the life of the battery, called their customer service and was amazed at their wonderful response. They sent me a new battery within days and I’m glad because the Tens has helped me so much with back pain. I would highly recommend this product and company.

Cannot recommend because…..
I bought this to compare with a much cheaper unit that I have owned for a few years. I cannot say it is a bad unit but I cannot recommend it either because it really does not do as good a job as units selling for just over $30. I really have tried to find reasons to like this unit. At first I thought there would be advantages to having a chargeable unit with no wires, but in practice this has not been advantageous. I should have returned it unused and got a refund because I had a feeling having read other reviews that this was going to be the conclusion.

Easier for elderly to apply then wired machines
Much easier than the wired machines. Battery lasts a long time between recharging.

Easily falls off!
I purchased this because it was ‘cord-free’ but I have gone back to using my old time corded TENS.This is a great idea but the pads come off way too easily even though my skin is clean and dry & free from oils. I use them for my lower back and when it catches my pants it falls off. I tried it on my upper arm and it still fell off. I honestly can’t recommend this product.
