Even the shittiest, most dirt-cheap knee braces aren't cheap. Wish I could afford one of those top-notch ones dfg.
I find the compression over my patellar tendon really helps. But the bottom of the line cheap-shit fabric, neoprene and velcro one I have is shitty, its fiddly, the strapping is too short to reach round and cross over the back of my kneecap properly, so I don't wear it very often, I want a top notch one like those dfg posted.
