Secure, but lock mechanism eventually seized
on 20 March 2012
Very secure lock, bracket to attach to a bike worked quite well. However, after 18 months the lock mechanism started to seize. Lubrication with WD40 hasn't helped. Often very difficult or impossible to unlock the bike, or put the shackle back in the lock and remove the key. The bolts that extend to keep the shackle in place seem to be the problem as they get stuck preventing the key from turning. A sharp tap with a hammer, or knocking the lock on a bike rack often releases them (when the key is inserted). Seem to be a few reports on the net of similar incidents.
Both Amazon and Abus have been unwilling to fix or replace.
