Slip the Cutter Commuter U-Lock in your belt and forget your bike thief paranoia. This hardened steel alloy u-lock is the U in the F U to the bike-thieving dregs of society. Simple, burly, and heavy enough to scare off motorists who know better, the Commuter owns the city streets. Cutter tossed in a couple of keys in case you lose one.
I use this lock on a daily basis to lock my commuting bike. Very simple to use and is beefy. I haven't had to worry about my bike at all like I used to with my old cable lock. It comes with two keys, which is a definitely bonus. The keyhole also has a sliding cover to help keep water out, reducing the chance of it icing over in cold, wet weather or getting rusty. I've used it everyday for the past 6 months (in the heat, rain, and snow) and it's held up. There isn't a single bit of rust and rubber cover doesn't have any wear. The lock is heavy, but that's to be expected with a solid lock. Bottomline: solid lock and great price. I would recommend it to anyone.
I dig it. Easy to use, comes with two keys. It's a little heavier than I'd like because I'm used to chintzy locks. Great product at a good price. Buy it.
