I have not had the same issues with knockoffs. I will agree the quality of Apple bands is superior however Apples level of quality is not worth the prices they demand. Its my opinion, and its yours as well or you would not have 46 knockoffs.
I am on the lookout now for a Nike style knockoff. I have an original Volt and bought a gray/black Nike knockoff. I can see that its not as well molded but it is more than fine and feels just as smooth. No one is looking that close at my watch or would say to me that a horrible knockoff band. For $15 its more that adequate as an occasional replacement. If apple offered an original it would be $150 and there is no way I would assess the added quality as being worth $135 more.
However, based upon some of the auctions I see that are selling original Nike volt bands others disagree.
