I recently bought very expensive (for my budget) wheels and tires - they cost me 2,000. >.< So I was extremely paranoid because someone was jacking up my bikes. I park my car at the bus stop to leave it unattended for 12 hours while I'm at work. Every day when I was without these locks, I worried a lot. It was nice to wear. Now I feel a lot better. I just hope nobody stole the whole damn thing.
