There is a fear that car seats can be weakened by being involved in a crash. My opinion is that it's way overblown, how many people have a serious crash with kids in the car? How many of them would then go on to resell the car seat? How many of those people would go on to have another serious crash to test the theory? That said, when it comes to protecting our children, it's hard to justify saving a few bucks.
