Quadrilla Marble Fun Set 2

I bought this marble run for my 5-year old grandson. He requested a marble run. I did not want a plastic one. I was pleased to find the Quadrilla. Right now, he builds simple runs. Yes, it still falls over occasionally because his coordination is not mature yet; however, he delights in what he creates. I believe he will master longer and higher runs during this year. He loves it! The wood is really nice. It is a work of art when set up. I am very pleased with the product.
