True, for its intended purpose it works decently. For what it has been used it is woefully insufficient. My understanding was that they have problems including a door lip which is liable to trip troops on exit from the vehicle, doors which have a tendency to become stuck closed prior to battle damage, as well the doors have a tendency to fail to close fully and which if not held can fly open when moving. In addition because it was not designed for armor, thus couldn't handle the up-armoring while remaining a capable combatant.
