use a name brand product, this is lousy
I tried this stuff because it was priced cheaper than some of the other big brands, and it was a waste of my money. The pad does not keep it's heat for a long time and the adhesive part does not stay sticky. Even when it heats up, it doesn't get as warm as other brands. There is no way you get twelve ours of relief out of this stuff. Spend a bit more and get a better brand.
