this thing is awesome I got it for my kid but it has me playing with it too!!! it's a must have I want to scream BUY THIS!!%23($("

Students loved these!

OMG my son sent me a picture of my grandkids playing with it I had to watch the video like four times cuz they loved it so much.

Great gift idea for kids who love to put together puzzles! Similar to the coin maze near the grocery store checkout counter, but watch the marbles race to the end.

So fun and easy to assemble. The light up balls are a huge bonus. They aren't as heavy as regular marbles so they don't go as fast, but they are really fun to watch in the dark. Consider buying another set to build a bigger track as the kids really enjoyed it.

This marble maze is fantastic! Not hard to put together. There are lots of pieces and you can be super creative in the way you build the maze. Then the LED marbles look really cool! My son loves it and I can't wait to use it with the kids I work with! Highly recommend this marble maze.

Came with a lot of marbles which was nice. The plastic is not very durable. We had a couple of pieces break. The pieces when put together don't snap tightly so you have to be careful because it can be knocked over easily. It was difficult for us to read the suggested instructions on ways to put it together. We found it easier to put it together with trial and error. It was a big hit for a gift. The kids love to play with it. I would recommend it unless you want to spend the money for a more sturdy long lasting one.

These aren't real sturdy. The U shaped base pieces in particular are hard to attach together and come apart easily. That said ...... They are enamored with this set and spend a lot of time playing with it!

Bought this set to combine with our many many Marble Genius sets. Appears to be compatible, but we bought it SPECIFICALLY for the orange plinko piece, which is hard to find and the purple and yellow swirl piece, which is not offered in any Marble Genius set. Sadly, neither of those pieces shown in the picture were included. None of the parts in this set are unique or interesting. We don't need them, so we will be returning this set.

Very cheap looking
