QiYi WuQue Mini 4x4
The QiYi WuQue Mini 4x4 is a smaller, more compact version of the world's most successful 4x4, the QiYi WuQue. The Mini measures 2mm smaller and has a fast, light and crispy feel making it easy to turn. The speed is extremely fast, but not uncontrollable, the corner-cutting is a bit over 45 after a few solves and some lubing, it is sturdy and stable, and it has never popped. This cube is absolutely amazing. This is the best 4x4 in the market.
