The cube is really dry and stiff when out of the box, however if it's set up with lubricant and loosened it turned extremely well. (Also sounds satisfying too lol)
The way to loosen it is to take off all center caps, and the center of where all the caps meet, the **** is in there. Please don't try to take the whole cube apart and reassemble it, I tried and it ended up being horrible as the end result and had to get a new one.
