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

Oh my goodness hours of fun! Awesome toy.

I love this item so much. Its pretty durable for kids playing. Something you as an adult can always play along with your child. I love things where you can get involved. Parents stay off your phones and off your work computers and be in your kids lives more and more. The best investment one can make that has kids

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

Hours spent creating!

It's not very high quality, several of the pieces, like the slide, the marbles fall of the edge 90% of the time. An occasional marble falling is okay, but most should make it from the top to the bottom. We got the marble genius race for Christmas and while not perfect it's quality is higher and my sons love it. Some one said that mindware was even better so I was stoked to get this for my 7 year old's bday. It came missing a piece to the box, and the marbles are constantly falling off the track even with set up on a level wood floor. I haven't bothered to test elevator yet but my hopes aren't high. I would try a different brand. Has anyone tried adapting pieces to work with a 3D printer by adding a better guardrail?

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.

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.

Packaging was torn and the plastic tub is missing a roller.

Item came completed except one of the box wheel was missing. Nevertheless we are having fun with it as a family. Parts are solid and well built.
