Not sure why the knock-offs couldn't add some sort of coating or make the material less prone to dust collection. I'm more than happy with my cheap and fairly well made Milanese Loop, and other 3rd party efforts. But when it comes to the Sport Band, I just can't get past Apple's originals. My only regret is not getting the yellow. I got a yellow knock-off and while it certainly looks the part, it's just crap when it comes to wearing it.
