I really enjoy solving this cube. Although the mechanism of the cube is very bad, once you solve it a couple of times it gets better. If you are looking for a speed cube do not purchase it, however if you are looking for a very small cube that is still fully functional and don't mind a few lock-ups, and a small pops then it is a great purchase, and fun to play with.

as much as i love my mini cubes and i wanted a 4x4 so bad, this one does not fit the bill for me in functionality. i am however willing to spend the money for just a cute piece of collectable plastic but i cannot expect to really learn on this unit. it began when i accidently dropped the cube on the floor from chair level(about 18") and the face of 4 of the inner cubletts popped off. nothing but a small male nipple to hold them on. need to be super glued. next mishap was when i got into too big a hurry spinning a layer and it hung and popped a piece out and the cubletts all fell apart. i was able to carefully reassemble the whole thing but with much care. i do love this mini 4x4 and truly hope that its popularity will cause a better manufacture of a 4x4 mini cube.
