Marble Run Toy Motorized Elevator Marble Maze Kit with Perpetual Motion Machine, Building Block Educational Construction Game Playset STEM Learning Hand Eye Coordination Training Unlimited DIY

My grandchild really enjoyed playing with this marble run. I recommend it. The elevator can get a little noisy. A simple way to quiet it, is to add a drop of oil to the bottom of the shaft.

My son loves this toy especially cuz it has a rotating cup. Easy to build.

This marble run works as advertised if you want to use it and set it up as pictured. The dinosaur pieces are challenging, but work as long as they are set up perfectly. My five stars are reluctant because my grandson wanted his own marble run, with dinosaurs. We wanted it to work with his sister’s marble lift tower. That only happened with a few hours of working and reworking and 3D printing of additional pieces (orange-red colored pieces in the pictures) and a 2x2 slide at the end. Since I was asking extra of the set, it was my extra work to do. It does what it says it does and therefore gets five stars.

My granddaughter loved this. It is a great STEM toy. There are a few problems with it...it is built on two flat panels. There is very little that holds the panels together and stabilize the whole structure so moving it is problematic . I went out and bought extra plain Duplo bricks to hold the panels together. We also used more Duplo bricks to reinforce the structure.

Bought one this Christmas for my 2 year-old granddaughter. She absolutely loved it. The marbles rolling down....very fascinating. Little rough to put together LOL

My grandson got this from for Easter and loved it.

Grandsom loves it!

This set is really fun, it works well and my kids are loving it. The balls are a bit smaller than I expected, they are a very chokeable size so that's something to keep in mind if you're intending this for a child who still mouths objects. Still gets a 5 star though. It clicks together seamlessly with brand name bricks too.

Works as advertised, durable, easy to handle, customizable. Only criticism is there are too many square blocks and too few rectangles. Better than typical building blocks is the balls movement when built right is a reward. Good for STEM education.

I do wish it came with a tiny screw to open the battery box

This is a good building toy...especially if you have young ones that love marble run toys. The more pieces you have, then the more fun you can have making different sets.
