It definitely has a fun and interesting feel to it. It is harder to read the colors because of the spheres. Don't expect to speed solve it because the spheres make it more difficult to manipulate. Shape aside it is smooth turning but it can be very unstable. It has mushy, squishy feel to it. It definitely will corner twist A LOT. This is because there is no way to really stabilize the sphere shapes in the corner pieces based on the design. Applying speed cube design to the spheres does not quite work out as well as what would be expected. I doubt adjusting the tension will make much of a difference. I have seen some people on video do it for speed solving. As a novelty cube it is quite a conversation piece and looks good in the collection. Buy it if you want something that is different that actually works. I got it because it looks like something right out of a mad scientist's lab. Neat - o.
