Great to have on hand
"I got these to have on hand mostly for human use. They are very malleable when cold, easy to wrap around joints. They also really held in the heat when used for heat therapy. Pay attention to the heating instructions though. I was lazy and didn't turn down my microwave power level and on the third interval heated them up too much. They are okay, but it took awhile for them cool down enough to be usable. I think I did 20 seconds 3 times, I probably should have done only twice at the current power level."
