Reminiscent of one of my favorite puzzles (MINE's Cube in Cage), Dinlas bumps it up from a 3x3 cube to a 4x4. Assembly is VERY tricky, with complicated manipulations at unexpected points. Very fun, very tricky, very attractive when solved!
Construction of this puzzle is excellent. All cube pieces are beveled, and the cage contains magnets which keep it nicely symmetrical in the resting position.
