The DaYan Megaminx Pro M is the first factory core-magnetic megaminx, it features not only the 120 corner-edge magnets seen in the DaYan Megaminx V2M which is currently used by many top megaminxers, but also 24 core-corner magnets which add even greater stability to the puzzle, the DaYan Megaminx pro M is also very lightweight, weighing significantly less than other megaminxes. This version is slightly larger than the standard version making it more inline with the standard megaminx size.
