The Rubik's speed cube is not in great. It has hollow pieces making a loud hollow noise. It's a very fast cube which in this case, is a bad thing. If I flicked the U face as hard I could, it will spin 270 degrees. The corner cutting is about a cubie normally and none reverse. This combined the speed is a bad combination. The cube also locks up quite a bit. The edge pieces just catch on the centre and ruins my solves. My average on my Aolong V2 is about low 17s. This cube takes it up to 20s. Overall, would not recommend this.

When I first got this cube I was unable to control it. I received 3 different springs for it and the mediums were still quite loose for me. Now I had only been cubing for a few months and was used to the original stickered Rubik's cube. It really is a nice speed cube. The only issue is that the holes between the pieces is quite small making it catch often. Other than that it is unpoppable and the sturdiest speed cube on the market.
