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. The Gan 356M is Gan's more basic version of the Gan 356 X, despite it being nearly 5 years old, it is still loved by many speedcubers and remains a popular and classic option.
