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!

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

It’s a lovely idea and overall reasonably good quality. You will need a lot of patience & perseverance to build some of those marble runs. Hence not sure this is suitable for most children under 10 or they need a lot of adult supervision and even the adults need a lot of patience! We used the side of our fridge and it works well. I would say magnets are strong enough. Overall, a lovely toy, but given that a lot of pieces are just plastic, I think it should be offered at a lower price

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.

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

Looks amazing - birthday gift not get given so will report later

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.

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

Lo compre para mi hijo de 10 años y le encanto. Funciona perfecto, nunca lo vi tan enganchado y entretenido con un juguete. La calidad me parecio buena, los imanes agarran bien, quizas hay que hacer algun ajuste despues de haber tirado la bola porque puede que haga pequeños movimientos sobre los imanes y no corre bien la proxima vez, pero es muy divertido

this is amazing to have on magnetic board or fridge great fun and creative ways to set up

Cadeau de noël pour mon fils. Il adore !

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

Il gioco è ottimo, mio figlio lo adora. Unico neo, ma comprensibile, ogni volta che una pallina cade, sposta un po' la corsia sottostante (essendo magnetico, non tiene perfettamente) e dopo alcuni passaggi delle biglie il percorso va ricalibrato.
