I didn't think I was going to like this product...but I was totally wrong, It was amazing...felt so warm and really did help with the cramps. they last at least 8 hours. Worth ever penny.

These are so wonderful to have! I have had some of the worst cramps that would keep me out of school and work, and leave me in bed with a heating pad all day. If I had to go somewhere, and it wasn't an option, these were what got me through. Even though I was still rather miserable, I still got some relief because I had these. It is like taking the heating pad with you!!! I highly recommend them.
