2"x2" - 200 pieces

I've bought the iStim brand before, but in a smaller quantity. I thought they were great. Really stuck on and excellent conduction.When I ran out last, I thought I'd splurge, buy a big box, and save some money in the long run.Well, I don't know if the larger quantity means the stock isn't cycled through as often or because they're putting the duds in these boxes, but they aren't nearly as nice as before. They keep peeling off. Like, as soon as I put them on. The edges start peeling up.I'm honestly angry about this. I spent like $77 bux on this box and feel like I've wasted my money.

great product

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.

... what I have found today upon unboxing it and putting it to use (only using ONE out of four channels...) is that the unit can be very powerful and kick your... yass, it can. That was very pleasantly surprising. It kicked the crap out of where I hurt on my neck and upper back. There are all kinds of patterns available, I tried some out until I found what addressed the pain best and I haven't even tried them all.I did turn it up into the 50s range, and if you put these gel pads on the right muscles it will cause them to work.I have needed this for weeks and thought the pain would go away as it sometimes does, but I broke down and but what I thought was the best one.I got what I paid for, and then some. I can't imagine what it would feel like using all four channels and pads... bet that would take away some stress.This unit is Quadrabiotic©!Would definitely recommend.
