Marble Genius Space Theme Marble Run, 200 Pieces, STEM Toy

Fun, durable. My grandson has played with this for years. I like it too.

I bought this for a 7, 5 and 2 year old about a year ago. It's still one of their favorite toys. They love to make different versions of the runs and love to watch all the marbles go through! They have a lot of fun with it! Highly reccomend!

Just got it in this morning and had to build it right away. Pieces are well made and connect easily but securely. Instructions are easy to follow. There is 4 different kind of marbles, plastic light up one, plastic glow un the dark, glass sparkle and regular glass marbles. All go into a black mesh baggie that's also included. My 5yo is already obsessed. Haven't even tried the app yet for challenges.

We purchased this set as an Easter present for my 4 and 5 year olds. Great colors, fun pieces, easy to put together. The pieces fit a bit tight for my youngest, but it stays together well with all those marbles running through them. The glowing and led marbles were a huge hit, and make this a super-fun activity for the whole family. A few of the led marbles weren’t working when we opened the box, but the company was really quick to respond to my email, very friendly, and rectified our issue promptly. Look no further - this is the marble set you’ve been looking for!

As a child I played with Marble Works sets like this and had a blast. When I bought this for my child, I was looking forward to re-living my childhood with him. Not going to happen with this. If you’ve never used Marble Works this might be okay because you won’t know what you’re missing. This set is light weight plastic and cheap. The balls are always getting stuck in the tubes because it’s so flimsy, any movement causes the tubes to bend at the connections. Marble Works is made of heavy duty plastic, and is solid when put together. Update/edit: the seller kindly offered a full refund for the product without me asking. Added a star.

this run has been great so far! not always the most stable of creations, but i think a good portion of that is on overambitious builds without utilizing enough of the provided supports and bases. we've had no issues with running out of bases or tubes or anything like that. the pieces do fit together well, though you may need to put some effort into some of them, mostly depending on what you fit together. i do wish the colors of led marbles were more evenly distributed (we got mostly red and yellow with only one blue and green each) but honestly as a biggest gripe it doesn't even really count.

This was a gift for a five year old, but ending up being tons of fun for the whole family, including adults! Endless opportunities and hours of screen-free and technology-free fun. It took some time to figure out the best ways to put certain pieces together for stability, but now it is easy. The kids especially love the light-up and glow-in-the dark marbles. We have already ordered some accessory kits as further presents.

Excelente, mi hijo está feliz

Before purchasing this set, I read so many reviews before selecting this one, and I’m so glad I did. My seven year old loves this set. I love a creative building toy, and this is it. He said he wants to give it ‘5000 stars’! When I had to contact the company about some flashing marbles that didn’t work, they went above and beyond to make it right, and in a timely manner. I am super impressed.

This may be the best toy I've ever purchased for my son. He just loves it.

Juego entretenido, didáctico, intuitivo, excelente para reforzar lo básico para niños.

We were missing one of the wheel pieces but otherwise this was one of my fave gifts. My kids love this and so do I. SO MUCH FUN. The glowing marbles are the best, they do have some kind of battery in there so be careful if you have wee littles that might what to eat that. Easy to build any way you want. Toy is not stingy on the size/pieces, like some other build sets, so the kids can really make it tall if they want.

Buena calidad
