MindWare Colossal Elevator Marble Run – 400-Piece Marble Maze Building Toys Set with Unique Marble Track Pieces, 150 Tubes, 9 Funnels, 50 Marbles and More with Wheeled Storage Bin

This is not my first marble run, but it's definitely one of the most sturdiest marble runs I own. It is very easy to build and to disassemble, and building giant towers with this marble run is great since it does not topple over easily. The instruction booklet is helpful, the whole marble run is colourful, and the storage box is great. What I like most are the 'super rail vortex' and the long entrance funnel pieces since these are really rare in the marble run market and they work flawlessly. I also like that there are many tubes and pieces to build giant structures.The elevator works perfectly fine too, however I received 134 chains instead of 135 as stated in the instruction booklet. This isn't a problem for me since I have some spare chains lying around from the other marble runs I bought in the past, however I think it is needed to address this packaging issue since others may not have spare elevator chains, causing the whole elevator to not work as a whole. I think it is also a good idea to include 140 chains or more in case a few are lost in regular play.

Kiddo's love it!! Gets them thinking when building and with never ending possibilities. Highly recommend!

Bought for my 4 1/2-year-old grandson. It was a great hit.

Bought this for my 6yr old grandson and he spent hours playing with it. He can make so many variations to the build that it teaches and delights at the same time.

My grandson has been completely intrigued with this set! He first built the set pictures on the box and then he decided to create his own design. Th at some challenges but he was motivated to get it working on his own.

Great for kids

This version is ver flimsy. The parts do not fit well together and do not stay together well. Tips over with little effort. Im very disappointed in this purchase. I would not recommend this to anyone for a child.

Overall like this toy! Love that it comes in a storage container that is sturdy. Our very creative 9 year gets a bit frustrated with the chain piece and finds it finicky but overall has still played with the rest daily for the last week.
