Kids can't quit playing with it. Glad it came with examples!

Awesome construction kit! Interesting and challenging enough for the older kids. The motor makes the kids play with this marble set for hours. Thank you:)

This is the perfect Christmas gift for my beloved father, age 78, who always made certain that his children received fun gifts on Christmas morning. I am delighted and can't wait to hear from him after Christmas. Sorry I won't be there in person this year.

My 6 year old son loves this toy. It was a bit challenging to put together, but he plays with it all the time. I would buy this again!

This is a great item that my 3 year old loves. He is fascinated by the moving parts and 'marble flow' patterns and has asked to have it reconfigured to another design already. The only drawback to this product is that it is not as sturdy as I would have liked but it is certainly something I would have still purchased.

An interesting mechanical structure. Fun to see the marbles go up and down. But it has some weak plastic parts.

Two thumbs up for your choice of educational products! This marble run is so much fun for my 8 year old!

Pieces are a little flimsy and a large design gets pretty wobbly. Really requires a good bit of thought and engineering to make a functioning design. Great mental exercise.
