Dinosaur Marble Run Blocks: 67PCS STEM Toddler Building Toy | 4 Dinosaurs & 4 Balls Compatible with Major Brands Interactive Race Track Educational Learning Gifts for Kids 3-8 Age

Bought one this Christmas for my 2 year-old granddaughter. She absolutely loved it. The marbles rolling down....very fascinating. Little rough to put together LOL

Favorite Lego. It’s really worth it. The quality is great. The colors are bright. It’s fun and creativity)

My grandson loved this birthday gift. It was easy to set up, took the abuse that a young kid could give it, and was a good price. Score one for Grandma!

Great fun for all ages once this marble maze is built. Assembly is needed for kids under 6 years old.

Adult needed for a 3 yr old to help assemble marble course. Very Cute and colorful fun toy! My child loves this fun toy. They watch the balls go down the couse again and again.

A great first marble run! My 4 year old is obsessed with marbles right now. I only wish it offered more options for building different versions of the run instead of just one. I like how the blocks can be used with other duplo blocks so we just added it to his collection. It’s a good educational value for teaching kids how to build, use their brains and be creative. Plus the bright colors are nice and eye catching!

This marble run works as advertised if you want to use it and set it up as pictured. The dinosaur pieces are challenging, but work as long as they are set up perfectly. My five stars are reluctant because my grandson wanted his own marble run, with dinosaurs. We wanted it to work with his sister’s marble lift tower. That only happened with a few hours of working and reworking and 3D printing of additional pieces (orange-red colored pieces in the pictures) and a 2x2 slide at the end. Since I was asking extra of the set, it was my extra work to do. It does what it says it does and therefore gets five stars.

18 month old grandson loved putting the marbles in the dinosaur mouth (with very attentive supervision since the marbles could be a choking hazard) and watching it roll down the track. Instructions for building the track are a little challenging- definitely not Lego quality instructions or pieces but still fun and good enough.
