Lawrence:. Awesome toy! Plastic pieces are strong. I know how people are breaking them. They are using them to remove a steel marble from the magnet cannon when they have it out of reach which requires a lot of force. I did this also and surprised the bridge piece didn't break but if it does break I won't leave a petty comment about it being weak, honestly forcing the marble off the magnet cannon should cause the bridge piece to break but I wouldn't use that little green part that catches the marble you only get one or two of those but that's how you break them...being stupid. These are so awesome, I'm buying a bunch of them. I dont mind the cardboard base either, kids might damage them but they're fine for big 40 year old kids like me. Can't wait to get the vertical pro kits, get those out soon!!!

This is the second set that I have bought for my grandson, he loves it. It's nice that one set is fun, but a second set can combine to give more options.

I'm a grown man who bought the XXL set and a few hammers, scoops, flip accessories to finally try my hand at marble runs again. Now, free hand build this is a lot of fun and you can make a lot of really diverse and gimmicky runs but the full potential of what you can create is unlocked with the help of the Gravitrax App which has a kiddie version of 3D AutoCAD for this set. That's right, you can design multi level, multi dimension runs of insane depth and tricks, test the runs out for potential flaws before the Real Life Build and then when you're happy with the plans- Follow the Step by Step picture Build Instructions to Built it! That's just friggin awesome.Highly recommended 10/10 toy.Note: The Gravitrax App design isn't fully account for all the real life chaos and variances which could mess up the marble run if the tolerances are too close so when you design your marble runs, allow for some extra slope/distance/wider curves/shorter curves/height differences etc so you don't waste timing building a dead run that only works in the App.

My 8 year old and I have been working on this together, and on their own as well. It's pretty cool, instructions are easy to follow, but I really cant believe i spent over $250 for some tracks for marbles to roll around on.

Kids loved it. The older kids were able to construct very creative marble runs.

My 9 year old Grandson loves this. He loves to construct different set ups and show it off to the family.It helps kids figure out how to plan a construction to make it work.

Me encantó este juego que además de pasarte horas armando las pistas, vas aprendiendo. Además puedes seguir comprando piezas de ensamble y hacer circuitos padrÃsimos. Otra cosa que.me asompro este que este juego cuenta con una app donde puedes armar tus circuitos y luego montarlos en fÃsico. En serio es muy entretenido.

Bought this for my 7 year old…he has spent hours and hours building & designing…an absolute hit! He already has an extensive wish list of expansion sets! Very well designed, the book gives lots of suggested designs & now he’s dreaming up his own! Would absolutely recommend this for any child that likes building blocks - next level fun!

Offert à mon fils de 6ans 1/2. Il ne décolle plus de ce jeu.Après avoir fait 2/3 parcours du guide, les améliorations "maison" arrivent vite.....Même si. Grand frère si est mis 👌
Brakowało instrukcji toru z obrazka na pudełku

Zawiodłem się na zestawie XXL. Brakowało w nim instrukcji montażu toru z obrazka z pudełka a gdy z synem układaliśmy tor po prostu na wyczucie z obrazka to okazało się że nawet nie ma w tym zestawie tylu elementów by zbudować tor co był na obrazku. Na szczęście dołożyło się z innego zestawu i zadziałało.

Fijn om samen met uw kind te spelen.Het boekje dat bij de XXL versie zit, zijn de standaard routes en worden niet veel uitbreidingen gebruikt.
