Not great
Don't be fooled by the &#34;XL&#34; in the name, it is not very big. Also, I have other gel packs that stay cold for much longer than this one. And the gel freezes so it becomes difficult to wrap around your leg until it thaws out. The hole designed to wrap around your knee cap is so big that most of the top of my knee is exposed, which is where I need the cold treatment for my meniscus repair surgery.
