In my opinion it is a very good cube.
The packaging of it he cube was good but I noticed that there was an awful lot of plastic which is always never good.
The cube out of the box was very dry and sandy and incredibly fast probably the fastest cube I have tried out before, but after a couple solves it slowed down to a speed which I can control.
Also the cube has a advanced core with a wide ability to customise which alot of MoYu cubes got going for them, but in my opinion the cube could have been a bit better with adjustable magnets like in the GTS and in Gan cubes but I got use to the magnets quickly so it didn't really make a difference to me but if it did it might have even better reviews and more purchases online.
In Conclusion out of the box it was very fast uncontrollable almost but will break in eventually.
When it does break in it is very good in a performance and customisability which is why I gave it a five star review.
Your sincerity Cubing Major. :)
