We love the heating pad XL that we received via a Groupon. I bought it as a Christmas present for my mother who has had more than a dozen surgeries on her back and she loves this one compared to her old one because of how large and soft it is. It's size provides comfort throughout her entire spine and the ability to easily wash it makes it that much better.
The only thing that's 'wonky' about it is the dial. When the 2 hr setting is selected, the heating pad stays on. When the setting for the heating pad to stay on is selected, it only stays on for 2hrs. It appears that the controls were mislabeled.
Anyways, thanks again for making a great product.
