Working great
I'm using a free sample that came with another product. This is super convenient with just the right amount of heat in the right place. It is lightweight and sticks on so I can go about my daily activities such as typing in this review. I'm going to buy some today.<br /><br />The people who wrote that it doesn't work either had a sample that had been exposed to the air, possibly with an improperly sealed pouch, or a very old sample. These ThermaCare pads get hot by oxidizing, so be sure to check the expiration date before buying...the fresher the better.
