Query: Not hot!

I've had this product for a year or 2 now and use it frequently in the winter to ease cold-related muscle cramps. I also have a Sunbeam and the difference between the two is night and day! The Sunbeam on high gets extremely hot, while the Conair on high gets...kinda warm at best. As for the actual pad itself, the Conair is very stiff when cold which kind of sucks when you're unrolling it but helps when trying to position it. The Sunbeam's pad is very flexible and comforms to you nicely, but is a pain in the a** to get to stand up on a chair without some sort of bungee.In the end, I would not recommend this unless you only want warm at best. It has, however, been quite reliable and never let me down even with almost daily use.
