The Speed Cube is a must have if you have kids or just want to "Get Childish". I bought the cube for my son who is interested in the Rubics Cubes. He hasn't been able to solve it yet but has gotten really close. We both like how smooth and easy it is to rotate the pieces around. I like that it is not your typical sticker cube. It came with a mini screw driver I am assuming so you can take it apart and put it back in order. I have not tried this out yet and don't plan to unless we can't solve the puzzle. Following the direxrions that are included with the cube are helpful and have gotten us to almost solving the puzzle. I am sure in a few days he will have it done. I received the Speed Cube for my honest and unbiased review. #Getchildish
