GAN makes the cubes many speedcubers race with, and the 356 RS is its entry model. It is stickerless, so colors never peel, turns smoothly with a honeycomb contact design, and cuts corners well so slightly misaligned turns still go through.
GAN's Numerical Core and GES system let the owner tune the tension by hand, without tools. For anyone still using a stiff toy-store cube, it is a revelation.
This version has no magnets, which most competitive cubers now prefer for control - someone already timing their solves may want a magnetic model.
Skip for a serious cuber who already owns a magnetic flagship cube.
