Review (1/5): It is comfortable and fits well but it does not stay warm ...
It is comfortable and fits well but it does not stay warm long enough. After heating it up it is very hot. When it is cool enough to tolerate, it then cools down so fast that you only can wear it for a few minintes. My doctor wanted me to wear it for 15 min. I bought the microwave one because I did not want another thing to plug in but I wish I have bought the electric one now.
