Thoughts on the puzzle: This cube has a really nice feel. Clicky, smooth, and controllable.
It also has great performance, with standard corner cutting (+45 degrees and ~a piece reverse when lubed) and little/no lockups.
This cube features squared corners, and while normally square corners means a cube will lockup, that is not the case on the YueYing. These square corners keep the YueYing from corner twisting. With the +300 solves I have done on this puzzle, I have never had a corner twist.
This cube has different center caps than normal cubes that allows them to be removed easily without taking apart the entire cube, which is nice for tensioning and hasn't been a problem in solves.
The only complaint I have is that my stickers were not very well placed (not the worst, but definitely room for improvement).
EDIT: After using the puzzle a bit more I am starting to have problems with the corner caps popping off (hasn't popped in solves). This can be fixed by gluing the corners down.
And On looser tensions with reckless turning, this cube can pop, but its rare, and can be fixed with tensions.
Overall, I love this cube and give it a 9.5(.5 less than my original 10 after more use, as I notice its slight flaws more)/10. It is my main atm (replacing an OP Aolong V2) and I love it very much. I would recommend this to anyone wanting a nice, smooth, controllable feel.
UPDATE (5/5): I still love this cube, but I wish I waited. This cube has a nice feeling but the speed is slightly lacking. I have been having more issues with corner caps popping (but I can glue those down) and also have been having more issues with popping at looser tensions. This is definitely a great cube, however if you want to get this cube you should reconsider, as it does get outclassed in speed by some of the newer cubes (Gans 356 and MoYu Hualong).
