I wanted a classic U-shaped bike lock at a good price. Bike stores have started selling more expensive, more complicated models. I like this one so far. It does the job and it still has a "tubular"-shaped key--which other manufacturers seem to be discontueing. I like the dust cap that closes over the lock cylinder too.
I can't rate its durability yet, since I've only had it a few weeks, but so far, so good.--B2
