    I bought this lock at a local bike shop with my bike purchase. This my first u-lock that I have owned, but I believe the 7 is a fair rating as the lock feels quite sturdy and the locking mechanism feels robust and turns without much issue. My problem with the lock is the included bracket. The mounting bracket comes assembled that consists of two pieces. The clamp that goes onto your frame and the bracket that holds the lock. The bracket is attached to the clamp with two screw that thread towards your clamping point ( in this case your bike frame). These screws are too long as they not just scratch your frame, but dig in and cause small gouges as you tighten the clamp. I place duck tape over the screw thinking they just might lightly scratch the frame, but the screws will push past the tape. I had to pad the clamping point to prevent further damage. It comes with a plastic insert, but that is just for smaller diameter clamp points. I have looked at competitors and they seemed to avoid this problem. Using the correct length screws would solve the issue, and the fact the issue exists is bit of a head scratcher. Fixing that issue would make it a great value lock.
