Not durable
These are some of the worst electrodes I've ever used. I've worn my TENS daily for a few years so I've tried lots of different electrodes. First of all I didn't even receive whats shown in the picture. The wire attaches on the long side instead of the short. Thats not a big deal but the problem is that the wire easily comes off the foam.  I will be wearing them and they will just separate.  This has happened to six of them.  Now I'm down to only 2 and I only received these about 3 weeks ago.  I take care of my electrodes, follow the directions, and they usually last from 2 weeks to a month per pair. These have only lasted a few days. Very frustrating! They do work well and are very sticky at first though.
