Query: Therabead Moist Heat

This product for the money is not worth it. It does not hold heat for more than a couple of minutes no matter how long you microwave it. It's bulky and does not fit into my small microwave. I used to have a homemade rice pack that held heat for and hour. It lasted 4 years with daily use. I guess I'll have to drag out the sewing machine and make another because that worked alot better than this overpriced item.
