Same brand but different? Not in a good way.
Use these quite a bit to combat back spasms. (3-10 four pad sets a week) The pads that came with the iStem 820 unit stuck longer / had better adhesive / adhesion. These pads aren’t as good. If I’m wearing then under firefighter bunker gear or I sweat even slightly they come off more easily than the original pads that came with the iStem 820. I made the mistake of buying 2 boxes of 200 pads wish now I hadn’t. You’ve been warned.
