From that site:


"Important note:

Buying a second hand helmet is not recommended. There could be damage you can't see. You are also unlikely to get the right fit. You must be cautious and only buy if you are satisfied that the helmet fits and is in a usable condition as designed. If you are in any doubt, contact the manufacturer for further information"

Now call me old fashioned here but I was always told DON'T buy a second hand lid full stop. I don't think the above helpful in anyway and is dangerous. I stopped reading after that point.
