The Gan 356M is a very nice cube, it is a bit too fast right out of the box but after a few hundred solves it slows down to a nice stable, controllable speed that is still quite fast. It does not come with any way of easily changing magnet strength and the default magnets are pretty strong.
This version does not come with GES nuts.
GES stands for Gan Elasticity System and gives cubers more set-up options on the cube.
I love the magnets and really improves my speed
One of the best cubes I’ve ever gotten. The customisable magnets are in sane
