FWIW, the newest KMC chain I own is a nine speed model, the "Nashbar nine speed chain by KMC." It comes with what is listed by Nashbar as a re-usable link. It looks virtually identical to a SRAM Power Link, and just like with SRAM links (8 or 9 speed) I've had absolutely no trouble removing or installing it, it can be easily done in a few seconds every time, by hand. I think there must be more than one type of "re-usable" KMC connector link out there. Every other KMC chain I've ever owned came with what I would call an old fashioned "master link," and those connectors are clearly not made to be removed by hand.
