The best thing about the Cube is the price!! I was a little disappointed in the quality of the Cubes,, it locks bad ,, I just have not tried to adjust it at all ,,, I am not sure it will!! But after practicing with better cubes then try to step down to learn on this one is not a recommendation that I would give it!!! I seemed like a good Idea and for others it may be but as for me,, you get a cheap cube that really doesn't seam to help me learn any better than my better cubes !!! The Locking is the main reason for the 3 stars,, For sure I can not speak for all,, some might get a lot out of the Cube,, and after a while of practicing I may change my feeling about the Cube but may not!!!
