This Review Title is works well for my old heating pad sleeve and the content is: Good product and a decent price but not as thick or as long lasting as the older simply cozy gel heating pads for the microwave. I like that these are USA made. The three pack a better deal than the single. They also came on time. It fits my old flannel sleeve.  I would purchase again as needed..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
