Lotsa fun
This is probably my favorite Rubiks puzzle. It hasn't fallen apart on me yet, and after several weeks of wear and tear turns quite smoothly. Solving the center pieces is pretty easy, and matching the edge pieces is fun to do; never quite the same combinations. And then you get to finish by solving it like the 3x3x3.

Challenging but Fun and Educational
The Rubiks Cube and the Rubics Revenge are both relatively difficult. The Rubiks Professor adds another level of difficulty compared to the other two. Like all Rubiks Cubes, they are made to last a long time and can take quite a beating. I recommend this if you are able to complete the Rubiks Revenge.

great puzzle like its predecesors
its a great game i also bought the revenge and of course the rubiks classic cube. i like solving it over and over just for the fun of it.

5by5 Rubik's Cube
I bought this for my daughter. She has already mastered the three by three and four by four Rubik's cubes. This was the natural next step. It is exactly what we expected. And she is close to figuring this one out, too.

Very nice
They should have invested more on the manufacturing, since a couple sticks were not exactly in place. Anyways, I do recommend.
