The QiYi QiYuan W2 4x4 is an upgraded entry-level speed cube with a very low price point. It feels stable yet smooth right out of the box. The QiYuan has an equal performance on both the inner and outer layers with a smooth and fast feel. The stable feeling and 59 mm size really set this 4x4 apart from others in its class. Great as an inexpensive first 4x4 for beginners.
