This puzzle is very fun, and it is really a challenge to try to solve. I haven't figured out a way to consistently solve the cube, although I was able to solve it once. This is a good challenge for someone who maybe has never tried an edge turning puzzle before. In the puzzle itself, the turning is super smooth, but it gets a little tiny bit locked up sonce in a while, but this is just due to the way that the puzzle turns. The bandaging with the jumbling moves also adds another fun factor to the solving of the cube, which is the main part of it that makes it difficult. Overall, this is a really fun and challenging puzzle with good turning quality.
