Sengso Magic Drum 2x2 3x3 5x5 4x4

The rotation is good, the assembly steps are intuitive, and there are no complicated formulas. The 4x4 version can be assembled as a 5x5, but if you do not pay attention to the hidden central edges, there is parity, as in the magic 4x4 tower from the same manufacturer. Thanks!

Puzzle assembled with good quality of plastic, soft rotations and not so easy to solve.
I'm very satisfied of my bought.

It is a nice puzzle. Waiting for the 5 layers version.
