I got mine yesterday. The grey is definitely more green than grey. Other than that they are exactly as expected. I do think the estimated 6 day shipping for 600 miles is a little long. It took 5 days to arrive, but only takes 3 days to get a JDM Seiko all the way from Japan!
UPDATE: I put the the grey/ green strap on a watch and the 2 keepers away from the buckle end are loose, floppy, and rattle. The black one is tight with no play or rattle whatsoever. Not so happy with my first MD purchase. Hopefully my second one will be better.
