Well made, not too hard; there are several challenges. The first is to unlock. Less than 5 minutes for an experienced player. Then there is the possibility to put it together with each of the the parts in the middle. Less than 10 for a good player, for beginners it can be a lot longer to find the solution.
Cheaply made, lots of burrs, but none that make it unplayable. The looks are prohibitive to gift it.
