The Apple SS link band is different from the knockoff's in that the butterfly clasp is flush with the inner side of the band. Really a precision design! The links changing for removal use a retractable connection but the knock-offs use a conventional pin that is difficult to change, usually requires a tool. The Apple one does not require any tools. Not that this is a big deal, just saying how they differ and why the cost is so much higher. But, for the money, I would buy the knock-offs.
