Got these as a impulse buy and been having SO much fun. Started with front
door Master Lock (easy) and just started working on my WRX (tougher). If you
are bored and looking for a hobby this is a pretty good life skill to
develop. After I get better I'm going to try making my own out of paper
clips!
