ComfytempOfficial TENS Unit Replacement Pads for K6114/K6122, 4 Pack FSA HSA Eligible Wireless TENS Pads, Reusable Self Adhesive Electrodes with Premium Quality, Non-Irritating Design

This Tens unit is saving the days with Sciatica. I place it at the pressure points and I can actually walk.

It's amazing they work like the other three sets that I had that have wires. No wires is a game changer, so easy just to slap it on. We even took it on a cruise. We have used these dozens of times over the last year. The sticky pads last months, or about a two dozen uses. But no big deal, we went online and bought extras. Battery life is great. Likely would last for hours if you were to need it, and we don't charge them every use.

Extremely durable. Can be used multiple times. Stickiness remains through multiple uses.

I love the patches and the tens unit, but they don't stick for more than a week or so of uses. Just wish the packages came with a higher count of patches.

pads stick well, effective current, masks pain well, and reasonably priced

This works well. I have a bad knee that will need to be replaced eventually, this device helps with the pain.I also suffer with back pain and the tens device with the back pain. Ive had it over a year and use it a lot, I just ordered more pads.

Pros: easy to apply, I like the sizeCons:Adhesive pads lose stickiness quickly, especially during workouts (sometimes only a couple of uses). To get the best results, wipe your skin with rubbing alcohol before applying. If a pad has lost adhesion, it may cause an uncomfortable shock.Replacement pads are sold only in kits that include multiple styles. I like the butterfly pad, but I end up paying for ones I don’t use since they’re bundled together.Adhesive quality could be better—I’d gladly pay more for higher-quality pads.With improved pad quality and more flexible replacement options, this would be an excellent product.

Excellent quality. Definitely recommend
