I like it and would have given a 5 star but it is very very small. I did not know they made them this small. I will more than likely repurchase for a larger size. Not much I can say about it is really is the Newton Cradle. Next time I have to focus on size when making purchase.
My five year old grandson loves to put things together and I thought this would be amazing since the marbles would be a cause and effect. The wooden pieces are difficulty to put together and stay so a marble can go down. The concept is great, they need to work on this product and make it kid friendly
