These two cubes are very nice, they are pretty much just as I expected, the Gan 11 M is more flexible than the Gan 11 M Duo and Gan 11 M Pro due to the lack of core-corner magnets, the Gan 11 Air is even less flexible due to the complete lack of magnets but also tighter from the factory. Somehow my average of 5 was actually faster with the non-magnetic verison but that is only one AO5.
