Believe it or not, this is the simpler iteration of the Quads and Rings series. Four wooden burr pieces interlock with two acrylic pieces with a level 13.5 solution. Doable despite the high level because a lot of the moves just follow. Achieving the checkerboard pattern is a secondary challenge.
Construction is excellent, with close tolerances but plenty of room to maneuver.
Note: Original packaging and documentation not included. This copy is made from Ash and Bloodwood, which is different from the production versions.
