The actual concept of this puzzle is thrilling and exciting to think about, but the general design of it is a catastrophe. Indeed, the puzzle moves terribly bad, when it does at all. Scrambling it was a nightmare, and I didn't even bother trying to solve it. It's very tight (probably due to its overall structure) and even doing simple 2x2 moves get the thing stuck if you are not 0.5° accurate in your rotation (and even if you are anyway).
On top of that, lubbing it doesn't seem to do anything better because the internals of pieces are hollowed, so the lube just vanish in voidy spaces and frixion reduction doesn't happen.
To purchase only for collection, but don't hope to be able to enjoy it as an "interactive" puzzle.
