NATIONAL GEOGRAPHIC Magnetic Marble Run - 150-Piece STEM Building Set for Kids & Adults with Magnetic Track & Trick Pieces & Marbles for Building A Marble Maze On Any Magnetic Surface

This kept my 12 and 9 year old quite occupied with a good dose of frustration while they figured it out. There’s a plan in the box to follow too and it didn’t scratch my fridge freezer either. Great purchase!

Good quality. The kids love it, only thing, there is nothing to actually catch the balls, so we have marbles bouncing on our tiled floor, a small inconvenience . Great fun

Got this for my grandson at Christmas, he and his dad loved this, making runs down the fridge freezer doors.

Good fun, but be careful as they slide around when left on the fridge. Unfortunately this lead to a couple of parts getting caught on the door and they broke. Could have done with a sturdier material maybe, or more care to be taken.

Amazing . Kids was playing for hours. However you must have a big fridge or create a steel wall

It is a toy, and I'm an engineer, probably I was expecting too much of it based on other reviews. The magnets are the weakness here, they are simply not strong enough. I had to supplement them with fridge magnets to enable reliable operation. The static elements that receive no shock loading are fine. However, when a marble drops onto an element, even a very short distance onto any track, or rotating, or other element, the element will move a small amount each time. without extra support. Fine, if this is to be used as a toy, but with this shortcoming, it is not possible to obtain repeatability over more than a few circuits due to the elements moving around. The fact that this comes with a lift, means that the elements need to remain where placed in order to provide cyclic operation. The marbles are also a weakness, none are spherical, just watch them as they roll! they are very poorly made and would be best, substituted for better ones. Overall, a great toy for a child, but not a gift for an engineer with expectations of repeatability.

Educational and doesn't take up space on the floor. Comes with a travel bag so you can easily take it to someone else's house. Pieces are sturdy and the magnets stick well. Instructions were easy to follow and encourage trial and error to get the pieces exactly in the right place or to make your own design.

My son is 9 years old and we bought him this for Christmas. This has to be the best present I bought for anyone. We have all had so much fun with it, the creativity to work out new runs learning to do small adjustments to make it work, it's been brilliant. We struggled getting the hang of the Catapult but that's just us, only downside is not being able to buy add ons. I wish I'd bought the bigger set but well will just have to get that next. Highly recommend this. Also we have used an old wipeboard rather than the fridge which has been perfect especially as we can move it around

Cadeau de noël pour mon fils. Il adore !

Este juego es impresionante. Mis hijos de 14 y 11 no paran de inventar nuevos circuitos, pueden estar horas...súper creativo, les hace pensar, dedicar atención plena y que ellos dirijan el proyecto que han diseñado, una joya que encandila a todos. Nosotros cogimos una pizarra magnética aparte y así pueden hacer los circuitos durante horas sin ocupar la nevera.

A super tool to help Littles learn about the push and pull forces of magnets! An education and fun toy that also helps foster imagination and creativity!

Buena calidad Desarrolla su ingenio, muy padre a mi hijo le encanto

This magnetic marble run is brilliant. Instead of fragile plastic tubes that fall over, these track pieces attach magnetically to vertical surfaces like the fridge or a whiteboard or fridge. The trick pieces add a ton of problem-solving fun, keeping both kids and adults engaged for hours, building unique mazes. Even after being brushed off the frig so many times, nothing has broken. The assembly is easy to complex, depending on the age.
