Key organization is the weak point of many everyday carry setups. Carabiners are often clunky, heavy, or both. Key rings suck. And if you have a giant key fob, it only makes matters worse. Then you have the problem of small S-Biners coming unhooked when you don't want them to. (I've temporarily lost my keys countless times thanks to dual-gated carabiners.) Those are all problems the MSTR LINX aims to solve.
