This is an extraordinary puzzle not just for its sheer physical size (5 inches to a side) but the fact that it features a two-worlds combination of straight lines (the 4x4x4 core) and curves (the six dials), the unlikely teamwork providing a titanic task to any willing solver. A great deal of work needs to be done to get just the 4x4x4 core straight let alone what's required for getting the six dials' pieces restored too. It's a high mountain of a climb and quite satisfying of a challenge to accomplish but I wish for all to know that this is a good fit only for highly-experienced solvers :).
