And the hardware is far inferior. I had a much more difficult time installing the A*S manis than I did the MSP manis. The A*S manis come with regular nuts and lock washers. There is one stud that you can't even use a lock washer on because there is nowhere near enough clearance for it. The MSP manis come with self locking nuts. The clearance around the studs is always tight, and A*S manis come with 16mm nuts. MSP comes with 14mm nuts. The size isn't a huge deal, but it definitely effects (affects?) the ease of installation.
