Query: Just another gimmick

While this does seem to ad a little support to my knee's chondromalacia condition, it's not that wonderful. It's hard to get comfortable and I constantly have to adjust it. It is also very itchy on the back of my knee in the bend area. Also don't plan on wearing this under tight clothing because it either won't fit or will stick out like a sore thumb. It is very bulky. Overall I don't feel it's benefits justify the god awful itching or the constant adujusting everytime I move my knee.
