I ordered 4 of these cubes to me and my friends. These cubes works perfect and it´s easy to turn and rotate the cube. The material is very good and does not feel like "cheap plastic" and the shipping and delivery was good too, I thought it would take too long to ship with the standard delivery, but it came sooner than I had thought.
I thought I would get them in black, like it is in the picture, but I got all of them in white. But does not really matter.
It also comes with a solving manual and the cube is almost 5 cm x 5cm x 5cm big.
