okay so i bought a pair of fks course on here last winter/spring and my buddy got a pair a couple weeks ago and i was looking at his and noticed they pivot a lot harder then mine and that theres like a semi circle plastic piece on the back of the round part that floats in there and mine doesnt have it.... so im wondering if im gonna premature with these since that piece is missing or if its not gonna make a difference and i can get shitty webcam pictures if you like
