Uni student here, and comprehensive insurance was out of reach. They quoted $3500 a year! Are they joking? This lock is basically my insurance. Paid $50 once instead of $3500 every year. It has already scared off one attempted theft (watched them try on the uni security cameras). Fifty bucks to protect the only way I get to uni and work? Absolute bargain. Every student should use one instead of being ripped off by insurance companies.
