Marble Genius300 pcs Glow Marble Run Track Race Extreme Set for Kids Age 4+, Glow in The Dark, STEM Educational Building Block, Color Instruction Manual, for Kids

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!

Super fun, transparent marble run set. Kid loved it with all the options, had plenty of action pieces and an over kill of connector/stand pieces allowing for great heights and and virtually unlimited options for a 4 year old. The marbles were the best part. Glow in the dark solid ones, ones with glowing bits inside, and ones with batteries and lights. You can watch them the whole way through and the color transparency material gets lit up as they pass. UV little flashlight is included.

Bought this for a five year old and it is a big hit. He spent hours playing with it. The marble run set is as shown in the pictures. Only complaint would probably be 2 of the 5 light up marbles don't work. Not exactly sure what sets them off, but if the child is happy than I don't care. Highly suggest this for marble run lovers!

Purchased for my 6 year old grandson for christmas. He loved it. Easy to assemble, sturdy, and lots of different marbles and some glow. Great buy!

Holy cow is this thing huge! When it's all put together, the functionality and sturdiness of this behemoth is great, it's not going anywhere unless your kid knocks it's down 😆 All of the light up marbels are battery powered and unfortunately they were all DOA and didnt light up. The only reason why I gave it 4 stars. And you can change the batteries but once it's opened up you need super glue to put it back together since they don't have any clips or prongs to help keep it closed.

I love playing the Marble Genius Glow Marble Run with my grandchildren. As a kid, I spent hours playing with my marble run and building different tracks. It's great fun to share this toy with my grandkids and introduce them to some of the older games that we used to play. I think it's really important for kids to play with different kinds of toys and games, and it's been really fun to go down memory lane with these marble runs. The glow-in-the-dark marbles are also a lot of fun, especially at night.

We got my five year old son got this Marble Run and he and he absolutely loves it. We are going to get him a second set so that he can make bigger runs. But we got it so that he can use his mind and imagination and that's just what he does. He problem solves, experiments, and has fun!

Bought for my grandson who loves it and is happy with it but the feature he likes the best is the light up marbles. Unfortunately upon opening the box over half the light up marbles were dead and the rest died by the next day which was a major disappointment to him. My query to customer support went unanswered so we’ll have to live with it. For this reason I don’t recommend this product and can only rate it two stars.I have to amend my review because the marble genius company has made up for the problem and i changed my rating to 5*.
