One of the things that I had to buy when I came to Cambridge was a bike. Of course, one also needs a lock. The clerk immediately offered me a Kryptonite U-lock.
- "It's the best product on the market, and most Americans are buying exactly this lock."
- May I open all the Kryptonite locks with the same Kryptonite key?
- Do the keys differ?
Incidentally, it may be a good investment for all car drivers to have these stickers, especially if you're afraid that the policemen will ever bother you.
We should also emphasize that sponsoring the Police Activity League is not corruption because they often play soccer with the kids from the inner cities. ;-)
OK, Kryptonite is a very bold company, and therefore they plan to offer you the "thick cylinder" part of the lock with a non-tubular lock and key, for free.
