Skins Compression Garments

I was wondering what people think of skins and other compression garments. Do you think they improve your performance, reduce injury rates, etc.?

Also, I read that there seems to be a trend between how long you wear them and muscle aches ( http://bjsm.bmj.com/cgi/reprint/41/7/409 ... Someone one he tried and he had much effect on muscle pain?

Sounds like the study says without any effect on performance, some decrease in pain. The problem is pain is subjective, what you call pain I can not call pain, some think it helped because they thought he should know better how is the try.
