Marble Genius Marble Run Starter Set STEM Toy for Kids Ages 4-12 - 130 Complete Pieces (80 Translucent Marbulous Pieces and 50 Glass Marbles), Construction Building Block Toys, Theme (Dinosaur)

These toys are excellent... We bought this and the booster set for our 3 year old son after he showed interest in building and playing with other marble toys. These are sturdy, and just perfect for letting him explore concepts like cause and effect and other STEM topics (baby experiments are fun to watch!). We were drawn to the glow-in-the-dark set because we envisioned using these in a sun room with strands of LED lights and our other space themed toys... They glow well, and the glowing marbles are a-whole-nother layer of fun.We've recommended these to the whole family... Hoping they also get some so ours don't disappear after family get-togethers.

Easily assembled. Sturdy. Good quality

My kid loves playing with this. You can make the same set up they do or create your own. My kid get so excited when they come up with something new and different each time. The color is nice and the quality of it is good. Keeps my kid entertained. I don't know if they connect to other brands outside of Marble Run.

Product is great for what it is intended for. Some pieces arrived in box uneven, possible due manufacturer oversight. With a little ingenuity, the problem was an easy fix. Love how it brings out the creative of my kid. Parents, easy win for hours of fun with the kids!

My 5-year-old LOVES these... though, I do feel bad that we have to limit play with it, because he has a 2-year-old little sister who loves to put things in her mouth. (The marbles could be a choking hazard).But my son has several sets of these and other compatible sets. He loves building them. (We can't wait until his little sister gets a bit older, and we can trust her a bit more not to put the marbles in her mouth!)

Nice dad son time.

I got this for my nephew for Christmas, and he absolutely LOVES it! It was a little tricky to put together, but luckily he was patient.

Kiddo is 9 yrs old , enjoyed building and creating, had fun

Did not receive good color, checked it out and seems flimsy, hard to be use by young kids... returned

Es una muy buena opción para regalo, a los niños les encantó, es bastante dinámico y muy interactivo, hasta a mí me entretuvo. Muy recomendado!

En palabras de mi niña fue el mejor regalo que le dieron los reyes magos. Puede pasarse hasta una hora jugando, viendo caer a la canicas de diferentes maneras. Tiene 4 años así que requiere de ayuda para armarlo y desarmarlo. Pero se ha divertido muchísimo. Estimula la imaginación y el ingenio. Para mí es un juguete STEM.

Incredible marble run, good quality product, and is pink my daughter love it, easy to assemble .
