I knew a guy that had a snap off steering wheel and the idiot lost the wheel, end up having to steer his car with a big pair of mole grips, or so he said, would have been good too see lol
The disk lock ones are V good, seen a few reviews ect with many different types of steering locks where some ex "pro" car theif tryed to get them off and the proper disk lock one always comes up 1st
