Well made & spins freely
I am really impressed by how easily this cube spins. The cube is very well made, and the colours are vibrant. I got it for my 10 year old, as he had expressed interest in learning how to solve it. The size is perfect for children and spins freely.Hope you find this review helpful

Smooth and durable
My son is a cube fanatic and he is constantly trying to create new patterns on the cube. This cube feels sturdy and I am confident it will be durable and be able to put up with his constant fidgeting with it.
