Bests & Worsts Reviews from Amazon

Had this lock less than 3 weeks and it has already prevented my bike from being stolen. Bolt cutters only put a small dent in the lock. The thief tried their best to drill out the side of the lock too. The lock is a bit heavy, but when you have the security of 16mm steel it's worth the little bit of extra weight. It hangs well down from my top tube. I have a Diamondback, so the top tube isn't a round shape - it still holds well. The bracket is plastic feeling, but seems to be relatively well built as well. Overall very happy with the purchase, especially since I still have my bike!! Sigtuna - should I replace my lock in this condition? Or is this still usable?
