- GraviTrax: Bridges Expansion Set | STEM Toy for Kids Ages 8 and Up | Compatible with All GraviTrax Systems | Ranked No.1 Marble Run System in The U.S

Very durable, fun toy

Exactly what he wanted for Christmas

Great set for children.

We've loved these marble tracks to pieces -- literally. The bridge set is a little delicate, but a fun mechanic!

This game is extremely fun and truly teaches a child or an adult to understand how Gravity affects the steel ball bearings and how bridges work! It also teaches a child how to follow instructions and ultimately, their own imagination. I’m a senior and my grandson is 11. I recommend purchasing the large starter kit first, then decide on these extensions.

My son loves these! Secretly, so do I. We work together and build the most complicated tracks we can come up with and then race marbles against each other. Great times!

Our 10 year old son loves these additions to his Gravitrax kit. Guaranteed to keep kids busy!

What's a brothers toy? Its a toy that two brothers can share and play with. Started last Christmas. Made some additions this Christmas. When they get tired of playing, they pack it up and put the box on the shelf. Then they decide that it's time to build something so they do. They experiment and fail, problem solve then succeed. Good toy.

my 8 years old loves it

Schnelle Lieferung. Der Artikel ist wie Beschrieben. Eine Super Ergänzung zum Grundset.

Genial juego. Se entretienen!

To add to the gravitrax starter set, this is a great game. We have enjoyed having this additional expansion having the more flexible tracks. They click together easily, seem sturdy and smooth for the balls to roll along and are a great addition. Could do with providing extra height tiles in every expansion though, as they are really needed to expand the set beyond the starter set.

Ho acquistato il set di espansione GraviTrax Ponti e devo dire che sono rimasto molto soddisfatto. Il set contiene tutto il necessario per ampliare le piste GraviTrax, inclusi ponti regolabili, binari e rotaie di plastica. La qualità dei componenti è eccellente, senza sbavature e realizzati con plastiche di alta qualità. Il set è stato un regalo gradito per mio figlio, abbiamo anche utilizzato l'applicazione di GraviTrax per simulare le piste prima di costruirle fisicamente. La spedizione è stata veloce e il prezzo del prodotto è ottimo considerando la qualità offerta. Ero preoccupato per la qualità delle giunture, ma sono stato piacevolmente sorpreso dalla sua solidità. L'ho montato e smontato molte volte senza segni di indebolimento.
