Gans Air SM is the improved version of Gans Air UM. Gans Air SM is the cube Feliks used to set the World Record average of 5.97s. The improvement is most seen in a magnet locking design that fixed magnets position more precisely and ensure magnets will not fall out of position when cube is dropped. The Air SM weighs only 76g and has a more natural feel about it as it uses 3mm by 2mm magnets. Each set comes with a full set of 7 GES V2 spring components, GAN full bright stickers, a GAN CFOP manual and authenticity card with serial number.
