National Geographic Magnetic Marble Run 150-Piece Building Set for Kids | Magnetic Track, Trick Pieces, Marbles, Marble Maze, Engineering Toy, Creative Construction, STEM Project for Kids and Adults

This was a very good Xmas gift for my grown son and his 9 year old daughter. They enjoyed it immensely.

good quality toy. it could use stronger magnets so the pieces stay put, but over all it is good

My grandchildren just love this package! Countless hours of enjoyment have been had all!

I spent 5 hours playing with this right after it arrived — it’s truly a genius product and incredibly fun. I couldn’t stop building and experimenting the entire first day. I’m giving it 4 stars instead of 5 due to a few design flaws: 1.The marble lift only feeds from the left side, which limits flexibility in how you can build your layout. 2.The magnets aren’t strong enough — parts tend to shift slightly each time a marble drops, eventually causing your carefully tuned setup to broke. 3.The motorized lift runs on a 9V battery, which is less common and more expensive than AA or AAA batteries. That said, this is still a super fun and creative kit. Just be prepared for a little tinkering and adjusting as you go.

Been a hit with the kids on my fridge for years

Fantastic idea, but needs to go back to drawing board for some strengthening tips so you get your $$ worth. Very very fun activity. I have it on the side of the fridge and every child that comes in has to inspect and play with it. I've created a number of configurations with all 6 of my grand children now. Each one having a blast. The poor reviews pretty much nailed all the issues I also had with the set.. but it's certainly worth more than a 1 rating. I wouldn't go above a 3 due to the expense of it vs the quality. Value? well it's not really for little fingers and frankly the pieces break, twist, or come apart very easy. They don't really snap in as nicely as you would hope so that adds to the difficulty of getting a working structure. Plus the magnet wasn't really strong enough to keep the pieces in place after 1 or 2 marble runs. Our set was missing pieces, one piece missing was vital to the battery operated Shute. We worked around that missing piece. but that was a bummer. I would have to say we got a ton of fun but 70 dollars is a lot to pay for something that's pretty much ruined after a few months, (and not because of rough play either). It's really fragile so it should be considered for older kids.

My grandson Are just obsessed with this marble run..will sit for hours ..together ages 8 and 13

I can't explain to you how cool this is... but realize that if this is a gift for your kids you are probably going be the one doing the work and putting it together... but once you do have it assembled in the way that you want, (ther is a learning curve), you will be able to swap out different sections, change up the route. You can create multiple routes that the marble can go. So yes. Its a great gift, but it is also a responsibility for whatever adult the kid belongs to. Assembly is simple enough after you get going. And if you're going to put magnets on your fridge, it might as well be cool ones that move marbles up and down and around.

El motor que hace girar la espiral principal no funciona

He spent hours playing with this thing. Magnet strength is tough. The sturdiness is a little on the bad side bc it is plastic material. It’s easy to set up and play with. The value for money seems too expensive for me but it did last long. It’s pretty big. Lots of things to make with it

Occore uno spazio magnetico grande per poter sfruttare a pieno le potenzialità del gioco,noi abbiamo usato la porta d'ingresso,ma veramente ben fatto. Ai bambini e a me è piaciuto molto,non semplicissimo da assemblare,ma ne vale la pena.

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.

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!
