What Others Say
sturdy lock
As far as the lock goes, all seems well. Seems sturdy and secure enough, with a safe locking mechanism (nice touch that you can twist the silver ring to cover the keyhole). The mounting bracket is not ideal, though. Depending on the bike frame, it's not easy to place conveniently, and the hold isn't quite as firm as I'd like it to be, even after tightening. And you can't release it again to move it to a different position.
Pleased with lock
I've only had my lock for a few weeks, but so far it is great. Shipped promptly. The attachment that holds the lock on the bike is pathetic-- definitely plan on having some sort of additional support to hold it on. The key fits pretty easily most of the time, sometimes needs a little jiggling, but opens beautifully once it's in properly. Overall, quite happy with product, especially given reasonable price.
bulldong bike lock
works fine, still have my bike a month later. knocked off all the plastic junk with a hammer and screwdriver to make it smaller. Comes with a big fistfull of spare keys, which is great, if you're a flake like me. so far the bracket to attach it to the bike needs to be retightened once in a while, and it doesn't really clip the lock securely, but i mounted it so gravity does the work. Many people complain that the breaks, so be careful how you're going to hang the lock off the bike.
So far so good
I've only used it 4-5 times so far. It's a strong lock and it's heavy, but I feel secure with it on the bike. The key only comes out in the locked position so you have to relock it before you can remove the key.
Jammed Lock
I've had this lock for a day now and the lock was jammed already. I locked this bike to a sign post and I couldn't unlock it afterwards. It took me well over 40 minutes to no avail so I went online to see how to get this thing opened. The other post that told said to "tap" on the key barrel is true, however, it's more like you have to hit it REALLY hard. If this ever happens to you, don't try to pull the lock because that won't work.
Other than that, this lock is super strong. I almost had to cut off the sign post to get my bike back!!
