The MoYu LiYing is a very good puzzle. OOTB, the LiYing is slightly scratchy and very crispy. Once broken in and lubed, this cube is buttery smooth and crispy. The turning is very fast and airy, but it is controllable. This cube does not catch on me, so my solves with this cube are very fluid. Corner cutting is around 50 degrees, and reverse is about 3/4ths of a piece.
The mechanism of this cube is very similar to the YJ cubes and the TangLong. The edge piece of the LiYing is very blocky. It has tracks, which allows the LiYing to be fast. The torpedoes ensure that the cube doesn't pop. The corner piece of the LiYing is very similar to the TangLong's corner piece. They both share the squared off corner design. The only difference is that the LiYing's corner piece has a hollow design.
