Review on 🦖 Marble Genius Run Dinosaur Starter Pack: An Incredible Marble Run Adventure by Michael Langelius

This is a birthday present for my 4 year old grandson. This immediately attracted him and he returned to him after opening other gifts. He played with it every day. It has some pretty tough, colorful pieces with real (i.e. glass) balls. There's a fair variety of shapes, although I'd like to see a shape that could split marbles by sending marbles from the same input down different paths. I especially like the swirl parts and the mill parts. I also like that the tubes are transparent. So you can see the ball going through the tube. You can build the sets by following the included instructions or, my grandson prefers, use your imagination. It takes a small piece of plastic to connect the base pieces, which is unfortunately fragile as one broke after just a few days of play. It's also not clear why green, yellow, and red refer to the colors of dinosaurs. Without the product page, no one would have guessed that these colors would make this set a "dinosaur".
