Comfytemp Official 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.

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

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.

So helpful. I've been storing them in the fridge between uses and has help pain and durability of the stickiness.

ComfyTemp tens unit works great, allowing you to target the exact spot that you need it. Battery lasts for several uses before requiring charge.

Excellent quality. Definitely recommend

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.

Extra pads for my cordless tens unit is a must
