National Geographic Marble Run with Motorized Elevator - 150-Piece Marble Maze Kit with Motorized Spiral Lift, 30 Marbles, Storage Bag & More, Perpetual Motion Machine, Marble Game, Kids Physics Toys

This marble run is fun and has an electric "elevator" for the marbles to travel up. We were initially missing a piece that connected the elevator to the run, and the seller sent the missing piece immediately. They were super helpful and stand behind their product. They also sent some extra marbles which was a nice surprise.

My 10 year old and 8 year old had fun with it. I watched as they put it together, so it wasn't too difficult to build. They enjoyed it and were able to break it down and put it back in the box for the next time they want to play with it.

These are well loved by all my kids! They provide hours of entertainment and every time you can create something new and different. This is also a great STEM activity for my classroom.

This is a unique marble run because of the motorized spiral lift, which provides more options than other marble runs as you build a run. Parts are well-made & sturdy and interchangeable with two other (different brand) marble runs. Two of my grandsons (7 & 6 years old) played with it nonstop for several hours the first time we took it out of the box! It would be helpful if, like some other marble runs, the guide had some sample runs to build.

Bought this for the little... ended up hogging it. The motorized lift adds nonstop fun, and the pieces are sturdy and easy to snap together. It’s educational, but also wild fun to watch marbles go on their rollercoaster adventures. Science + satisfaction = 5 stars.

I have a son with ASD and he LOVES it! It stimulates his mind and he’s always looking for new ways to build it!

Excelente juguete para niños

Great quality set. Wish there were more of main pieces to built with though.
