Review on Reliable Security with ONGUARD Doberman Resettable Combo Coil Cable Lock by Jamal Murph

The Onguard 12mm cable lock is a very reasonable compromise between security, convenience and price for most people/cities (but not for bikes which shouldn't be left outside anyway ;-) Rolling rotate easily. Contrary to what has been reported, you cannot find a number by trying to "catch" it. I don't think it can be cut with regular bolt cutters (you'll need to use a power tool). Unlike U-locks, it can be tied not only to posts, but also to lampposts, trees, etc.
