It's a real downer to come out of a class and realize you have to walk.
Kryptonite makes good locks in the same sense that Trek makes good bikes. They do both make top-of-the-line models that are tops in their respective industries, but they also make pieces of trash for people who just want one to say that they have one.
Even the best locks in the world can be compromised, but it usually takes special equipment, a lot of time, and/or is not worth the risk. Bostontrevor is right, take off the aeros, and that bike will treat you nice.
