Query: Makes me feel safe when I leave my laptop unattended.

This lock is very easy to use. the only two things you need to carry around are the key and the cable itself. Tie your laptop up wherever you go, especially the library! I live on the ground floor, and my desk is right next to the window. So I keep my laptop locked up even when it's at home, so that any would-be burglar would have a tough time breaking the window and taking off with my notebook. Although, if he really wanted to, he could probably get a pair of wirecutters powerful enough to cut the cable.All in all, this cable makes me feel secure against casual thieves and I recommend it for all laptop users.
