The Rubik’s Professor Cube is made from a hard black plastic. The object of this puzzle is to scramble
all 6 sides of the cube and then return it so that each side is only one color. This is the most complex
puzzle from the Rubik’s Cube series, providing an extra challenge because it is 5 layers deep in all
directions. The first Rubik’s Cube was patented in 1975 under the name “Magic Cube” and was
changed to “Rubik’s Cube” in 1980. Since then, Rubik’s has been designing and producing many

"Newly tooled" is extremely good news! I bought one of these roughly two years ago, and it was so horribly stiff and uneven in torque (also unlubricated) that it was a disgrace to the good name of Rubik (It was a genuine Rubik, very likely). One would get RSI from attempting to solve it. Tooling was, well, essentially careless; it was possible to turn it, but that was all. When I complained to the vendor, they sent me a replacement that was just as bad. I did try to disassemble it; the center cubies were sealed (solvent, thermal, or ultrasonic welding?) so one couldn't get at the screws (no complaints about that). Without access to the screws, it couldn't be disassembled much. That one's mechanism had been elaborated somewhat, so it was very unlikely to start to come apart; it's likely, though, that this one has that same mechanism, properly engineered in detail. I have quite-high hopes! Please evaluate this one's appropriateness for speed cubing. If it qualifies, that's just great! If it's tiled, instead of having just stickers, that's even better. I rated it 4 because I haven't seen nor tried one out, yet.
I just bought this puzzle yesterday. I have no complaints :D. This is a great puzzle, it turns well and everything.
The Rubik's 5x5 is a great puzzle, but without knowledge of the 3x3 and 4x4 it would be quite difficult. If you have already mastered the Rubik's cube and the Revenge I highly recommend taking a whack at this one.
