4.0 out of 5 stars Strong but heavy lock., January 3, 2007

Lock is very sturdy and has quality steel construction. However it is a little long so if you have a small frame, chances are you won't be able to hook it onto the top tube. Since it is so long this also makes the lock very heavy. The locking mechanism jammed about a month and half after using it. However, Onguard's customer service was very good and they promptly sent me a new one after sending defective one back. Overall, a durable lock for the everyday bicycle commuter.

OnGuard makes the best bike locks that I have seen and their prices are about the same as other brands. This particular bike lock has dual locking cylinders and would be virtually impossible to break. The quality is excellent and the lock comes with a full set of five keys.

3.0 out of 5 stars Beware the CRAPTASTIC mounting bracket, January 29, 2011

This u-lock is pretty heavy, which is to be expected. But the mounting bracket is made of really cheap plastic, so it only took a week for the bracket to break off. Totally useless piece of crap.

The u-lock itself is solid though. Just be aware that you're going to have to carry the u-lock in your bag.
