Very nice cube! It turns smoothly, especially for the complex mechanic. Although you sometimes have to align it to turn the edges, which can get a little bit complicated. It jumbles, which makes it even more difficult to solve. Even turning it into a cube is rather complicated, since the jumbled pieces block some movements. Also, the jumbling generates new states, which can only be solved by using jumbling again. It is rather difficult and I spent quite a long time with it, it is probably the most difficult cube I have had so far in my collection. You will need patience with this one, but I can definitely and without hesitation recommend it!

The skewb layers turns smooth, although the colver layers must be correctly aligned to turn them. I haven't managed to solve it yet, but it seems to be a real challange. Hybrid puzzles are usually harder than just more layered puzzles with same amount of pieces. For example, a Flower Copter (which is a Curvy Copter and a Redi Cube) is much more difficult than a 5x5x5.
