They work great.
They work great,last a long time, and if I just need them for a few hours I just put them in a zip lock bag, then when I need them again , I take them out of the bag and they heat back up again. They are a quality product, last a long time, and are a much better price then the brand that I had been buying. I will keep buying them because I have a lot of trouble with my lower back pain. They really do help with the pain. They are saving me a lot of money.
