Query: Worst mouning system EVER

How good is this lock? I don't know, but I do know that I'm very likely to forget it because I can't mount it on my bike. Every u-lock I've ever had before went on my bike by just slipping the lock into a bracket and pushing a lever. This one has a cheap, cheap, cheap plastic mounting system that straps on (and undoubtedly UNstraps easily. It wouldn't fit on my new bike because a) the top bar is too thick, b) the brake cable goes under instead of on top of the bar, c) I couldn't mount it on the front bar because of the gear cables d) and it wouldn't fit ANYWHERE because the mounting system keeps it too far away from ANY bar and you have to have a LOT of room above it to be able to snap it on and off. FORGET about leaving your water bottle holder on. It won't even fit with it off. I guess it's not as bad as making a lock that can be opeed with a Bic pen, but COME ON guys!
