It's a fairly decent cube, it moves pretty, it's pretty crunchy, and it can corner cut to some degree. Although I wouldn't recommend that it be used as a main or for any other purpose other than as a novelty for your collection or to wake up your neighbors. TL;DR It's okay but very loud.

The Huanying is the first released my Moyu. Despite how old it is, it is still a decent 3x3. Out of the box, it was springy, loud, and crunchy. It came with the Moyu shades and I have since replaced them. After lubing, tensioning, and breaking in the cube, it is still rather nice. It has a bumpy crunchy feel and it is overall very loud. The corner cutting is alright. It can do 45 normal and 2/3 reverse. Lock ups tend to happen due to the design of the cube. Corner twisting is also likely to happen depending on your tensions. Overall, it is cube with fair performance.
