The powerful performance of GAN356 AirSM was testified by the 5.97s World-Record from Feliks, in June, 2017 This highly-anticipated successor to the GAN 356 Air UM features an all-new design that has been optimized for magnetization, with specialized slots for holding the magnets, a new and improved elasticity system (GES V2), and a unique honeycomb design on the pieces. The Air SM feels very fast and quiet right out of the box. Each Air SM comes with a full set of 7 GES V2 spring components, GAN full bright stickers, a GAN CFOP tutorial pamphlet, plastic adjusting tool, and a GAN 356 Air SM VIP card. There are 48 magnets in total in the GAN356 AirSM. The whole cube weighs only 76 grams, which is almost the same as the Air and AirUM The innovative world-first honeycomb contact surface is designed to make lube equally spread on the contact surface, resulting in a very smooth and stable handfeel, and a longer life-span of the lube. The IPGv4 is manufactured by injection molding, using both the ABS and the core axis screws. The core axis screws are accurate with a diameter of 1.90mm+-0.02mm. To adapt to the precisely-designed GES v2, the screws must be more stable, and more vertical to the neighbour axis screw.
