Good for the Guarantee
I have only had this lock for a week and used it pretty much every day so far. I love that it lock comes with a 4,000 theft replacement guarantee, which is really the main reason I purchased it. It is a bit on the heavy side which is my only real complaint. the scratch resistant material is one of the few that actually holds true. I have used it both on a carbon frame and an aluminum neither having marks on them afterwords. Even if it has been a little tight squeeze. Overall so far I am pretty satisfied with the lock.
