my neck needs this. It smelled at first, and needed to be rewarmed after 15 minutes, but I can relax and ease  the spasms with this and positioning.  I won't give it up give it up. The material is super soft.  It is a bit heavy, so you have to position yourself so the weight of it won't add to your discomfort. Wish it was long and wide enough to go around the lower back too.
