After using these electrodes I find that: 1-durable you can use each one about 10 days in clean skin and it will stick with skin in nice condition. 2-the quality is very good because the dimension 2"x2" and thickness is very suitable and comfortable to move it from one area to another. 3-does not irritate my skin 4-works with my old unit 3-fast shipping in well condition from this company thanks

Of all the electrodes I have tried,these are the best! They also arrived very quickly. I ordered them on a Saturday and they were delivered on Tuesday.

My knee has been acting up so I pulled out my TENS unit one night and found that my electrodes were in no condition to be used. I searched the internet and found these electrodes which I ordered at approximately 10AM. By 4:30PM that day I had a tracking number. WOW,that was fast. Only two days after that I had received my order. So far I have been very impressed with these pads. They are very comfortable and seem to be almost identical to my favorite reusable pads I purchased made by 3M at 4 times the cost.
