The concept of compression and heat is a nice thought. Perhaps if they made different sizes of the sleeve I’d have a better review. I don’t know if that would help. The heat is only a 4” x 1/2” vertical strip that is supposed to sit over the top of your knee/patella. When the compression is on, it causes the heat strip rise, the heat is not able to penetrate through the compression. I had hoped that there was heat in the other part of the sleeve that can alternately can be placed over your calf or thigh, there’s not. I could not get the sleeve to fit close enough to my knee to feel the heat. I tried all 3 heat levels. I couldn’t feel the difference. The compression felt ok. I’m returning this sleeve in the hopes an exchange for a new one will make a difference. Also, the website says that a travel bag comes with it, it does not.
