I've been using the same pair of electrodes since I received them on May 25th. They showed no signs of wear. I use them almost every day, so about 20 by the most conservative estimate. They don't irritate my sensitive skin. They are good conductors. I don't know what else to say other than I will definitely buy them again if I need them.
