I've been riding Autos (and most recently the Auto Evers) for going on 3 years now. At first I was skeptical because the first series kept breaking. Honestly though, when they worked- they worked awesome! After getting mine back from the recall, I've had no issues at all with them. As far as these compared to the K2 cinches- the cinches are cool too- one of my favorite ridin buds rocks em and swears by em...However, when it comes to malfunctions and the fact that they tear up boots the K2 auto wins hands down. The Auto is lighter by 30%, less parts to break, and a hell of a lot easier to get in and out of in deep powder- bottom line, get em- if youre disappointed you can punch me in the face!
