The new 2019 QiYi Sail W is a great budget speed cube and an upgrade on the original Sail from QiYi. Importantly this cube is tough, and can better cope with with knocks and drops and is the speed cube which closest resembles the strength and toughness of the original Rubik's cube whilst still 'solving' like a speed cube.
The new Sail is really a sound choice for everyone's first Rubik's cube and has surprising quality and performance for this price range -making it a great trainer cube for the classroom, gifts or 1st cube.
