The cube is not good at all. I bought it just to learn how to solve a 4x4. It is not suitable for more advanced use.

It does not turn easily at all. Corner cutting is practically non-existent and it constantly gets stuck. At least, I haven't had any pieces fall off yet, as has happened to others in the reviews.

It is not the cube shown in the picture, but that doesn't bother me. The problem is that this cube doesn't turn easily, and the cubes come out easily. If you handle it with caution, it won't break.
This cube is good for its price, but there are many other options available.

Very good cube for its price, however if you twist it too abruptly, the cubes may come out of their position. Nevertheless, if you handle it with care, it is a pretty good cube.

Very good without stickers in the colors, which in other cases come off. Very fast turning without sticking.
