Rated 5 out of 5 by from High quality lock I bought this lock after having a cable lock cut (luckily the thief was interrupted before they took my bike) and campus security stating a U-lock was the way to go. Looked at different products (and bought a few as well) but this product stands well above the rest for security imo. Would buy again. Pros: Very secure Good mounting bracket for bike Weatherproof cover for key Con: Heavier than anything else I tried - if you have to carry it on your body, you will know it!

Rated 5 out of 5 by from Solid lock, easy to transport Very easy to transport with included frame mounting kit. Luckily, it hasn't been put to the test, but the lock feels much more secure than prior locks I've owned. The key replacement program Kryptonite has is comforting.
