4 years ago I crashed when taking a turn too quickly on damp pavement and hit my head. I was wearing a 2 week old $275 helmet and the shell was cracked.
When asked if i was upset that a new helmet was damaged, I said it did it's job and kept me out of the ER. Giro gave me a a crash replacement discount and the LBS added to it, so a new replacement was half the price I originally paid.
