I just bought this thing last week, I've used it for exactly 1 trip to work, this being the second. I had it on the seat because I didn't want to put it on the ground. Well I forgot to take it off when I went to cover the bike since it sits out in the sun all day and I start covering and then hear it slide down inside the cover and them BLAM right on the concrete. Now it's scratched in the back and a piece of plastic is cracked. It didn't fall hard enough to compromise the integrity of the helmet, just enough to do damage! :crying:
