Good quality and smooth teraminx. However, please be aware: it is smaller than it seems based on the photos, about the size of a large grapefruit. The only new challenge here is that the center pieces can not be completed with a cubic center-piece commutator; the 3-cycle on a 6-sided polyhedron becomes a 6-cycle on a 12-sided polyhedron. however, with some planning and setup moves, this issue becomes easy enough to rectify, if not more involved.
