1) Dual Adjustment System: upgraded with 5 levels of elasticity & tension, new comers can get fast turning speed.
2) Positioning with 48 magnets: offers better stability & corner-cutting; improves smoothness and fluency.
3) Concave ball structure: makes the cube lighter and reduces stress during practice.
4) Improved anti-pop torpedo: triangular design at the end of corner piece with an extra layer of interface inside which prevents piece popping or jamming during fast turning.
