Fun toy for kids to use! Stacks well and kids learn from play. Love that it has a bag for the marbles. Easy to clean up and easy for kids to use

*Updated: The more we play, the more frustrating this set is because the pieces like to fall apart very easily if you’re not great at creating a stable creation which results in a frustrated mom and boy. Keep that in mind if you’re child wants to do it independently and is also new to marble runs. That aside, it’s fun. I just wish the small set had more pieces, especially bases to keep it stable to be able to create different designs.*_______ So I gave this a 5 star because although it didn’t make me feel like it’s amazing, it’s great for the price and quality. Our son loved it this morning during Christmas. My husband and him built a few drops. Pros: easy to use, marbles are pretty, the light and glow in the dark feature was a hit, and you can achieve a few different drops with the amount you have. Cons: This isn’t the most sturdiest set, seems to be easy to snap if you have an energetic child like ours so be careful, and wish they have come out with an expansion by now. Over all this is fun and the kid loves it!

I'm always looking for a good STEM toy, and this one delivered. It allows my daughters to learn, create and have fun all at the same time.

This a decent set with parts that easily fit together to build any tower that you can think of. I enjoy the fact that the colors are transparent and the marbles glow in the dark. Depending on where you place this marble run, the marbles move through the set's tubes quite nicely. I suggest that you work with it on a table or firm surface so you won’t have to use your hands to hold it down. I attempted to use this set on the carpet, but it was not stable enough and almost fell over several times.

JD loves everything there is about the National Geographic Marble Run he received for his birthday, so what could be better than ways to make it bigger and better, and more complex! Great mind builder, problem solving and entertain gift..

We absolutely loved this gift for our 4 year old granddaughter. It was fun for all of us to make different runs with it - she really liked the creativity of it and the flow in the dark marbles. I also purchased more marbles and it's really fun watching so many take different tracks. Only criticism I will give is that it's not super sturdy it good enough and if it does fall , the beauty of it is , you can set it back up or make different one !
