A mate of mine bought one of the cheap carbon frames, it arrived damaged, he sent it back in the same box and they complained it wasn’t packed suitably 😆
(otoh my C456 came with the dropouts not attached, to avoid this problem, but none of the hardware needed to fit them, so the frame sat unusable for a couple of weeks while they got their act together. Apparently it was the first time it had ever happened and they struggled to believe it could occur, though when it happened to some dude on bikeradar a month later it was the first time then as well and they were just as astonished)
