May I ask why you don't trust it for something longer? I'm asking potentially for my own good haha. I would think that you would at least need power tools to break this lock in a reasonable amount of time (as opposed to hacksawing for an hour). Especially since it's a mini lock- which means if used properly you shouldn't be able to fit a jack in there. As a deterrent- it has the benefit of being from one of the two trusted lock brands- and it feels and looks solid. Also, if a thief DID bring power tools- you weren't going to save it anyway. I certainly don't understand why it would be more risky to leave it out there more than 10 minutes. Again correct me if I'm wrong- I'd love to know if I'm missing something (as I may change my mind on this lock).

Now I'm not saying you can leave it overnight someplace, but I think in relation to the OP's situation it would do the job pretty well. I'm assuming he would be parked on a bike rack alongside other bikes, many of which will not be secured properly. He'll have it there for class (maximum of about an hour and 20 minutes before a break). All of this on a college campus. But I will admit if he wants the "best lock setup possible" this isn't it. I think it's a good balance of value versus function.

*Which reminds me. OP- be sure to register your bike with the campus police department. It could save you a lot of trouble if you do have the unfortunate circumstance of getting your bike stolen.
