Title: big relief, but almost too big to fit in the microwave
Review: Got this for back pain and for post op knee and shoulder surgery.Pros: Stays warm for a couple of hours. Be careful when putting it in the microwave, and DO NOT allow any edges to touch the sides of the MW or it will catch on fire and melt a little hole in it.Cons: Does not stay cold for very long. Expensive. Buy a smaller size if you can.
