WEofferwhatYOUwant Marble Run Set – 169 Piece Marble Track Tower Building Game for Kids Ages 3-8+ – Creative STEM Maze Construction Toy – Educational Building Blocks for Learning & Fun

Worked perfect for a Christmas gift. Not the best of quality but works fines

these tracks are about 5 inches long and the tubes barely fit around my pinky. the bases are so small my son’s hand knocks over the whole tower when he tries to retrieve the marbles, and the tower isn’t very stable to begin with. the pieces don’t have enough lip to snap together and want to stay together. not worth the money unless you have kids with extremely delicate hands

Kids loved these

The media could not be loaded. My boys enjoyed this. A little hard for them to put together. But once it was done, they had fun!! Ages 4 & 12

All the parts are small. The instructions that come with it to build it is useless and the parts aren’t sturdy, falls apart when you kids reach over for the balls that runs to the bottom. Disappointed.

this would be a great starter set for a kid but it's not durable like the genius ones, this sets pieces are smaller, if you step on a piece it will break, and its not sturdy at all. We prefer the genius brand they are bigger more sturdy pieces.

Product small than expected but did not ship in a box just shipped with no package

I'm sure the set is otherwise fine, but disappointed to discover this uses custom marbles that are not standard sized (15/32" vs 9/16", weird choice). Was hoping this would be compatible with other sets we have purchased, but these tubes are tiny with outer diameter of ~18mm and length of ~35mm (~29mm when connected).
