this is the status in which i found the tail of my acid just the moment after i pulled it out from the package. Dependind on the fact that the nose and tail are extremly well protected by the packing i was wondering if this could be a factory problem more than due to uncarefull shipping.
and then there's something else, sometimes when i press over the heel bumpers, i hear a CRACK CRACK sound. Is it normal or what else could it possibly be?
as i said the board was just opened, so nover in water nor misused or anything
