"It may be user error or this lock just might suck."
I'm not an idiot. I read the directions and followed them to a "t" and was unable to set the lock properly. After 30 minutes of this I may have had a temper tantrum and thrown the lock around and somehow set it to an unknown number, making it useless to me. I've read other reviews by people who had the same problem so I'm still not convinced it was total user error. Also, any monkey with a wirecutter could cut through the cable. Its very thin and fairly useless. You're better off getting a bike lock!
