The first one we had to break, as it got stuck, with the key in it and I needed the bike. So a kind man broke it for me. I think I have photos of it up on this blog, too.
The second I had to break myself - with my two little hands. I stole back my bike, which was stolen from me!
My thief or even somebody who bought this from the thief was using for my luck a really shitty lock, so I got it back. Thank god!
