RavensburgerGraviTrax PRO Vertical Expansion Set - Advanced Marble Run STEM Toy | Encourages Experimentation and Creativity | Compatible with All GraviTrax Systems | Gift for Kids Age 8+

I really like this product, but it feels less sturdy than the original GraviTrax set that my son has - the box is made of a thin cardboard so we have to purchase something different to store all of the pieces in.Great set though - - lots of fun ways to experiment with gravity and magnets and it works seamlessly with our GraviTrax entry set.

Definitely levels up the track play (literally). Kids really enjoy the addition!

Quality product

This product is a great addition to the base pack of Gravitrax. It allows you to build up higher so you have more of a gravity assist and faster track. My only complaint is that once you have this expansion, it feels like you need more of the basic parts to make a bigger track.

My Grandsons have building GraviTrax for several years. They have two full sets and still couldn't build as high as they wanted. This is a terrific shortcut to build high and they love it!

Fun!!!!!

My son is a LEGO enthusiast, to put it mildly, so he doesn’t often find himself attracted to other toys. However, he received the GraviTrax base set as a Christmas gift and loved it. It gave him an opportunity to use his LEGO building creativity on another type of project. We bought this set so he could build taller and more elaborate GraviTrax models. It’s definitely become a favorite with him and his friends! We hope to continue adding expansion packs so he can build truly impressive and complex models.

The vertical expansion allows track designs that were impossible before. And some of the tower pieces have tunnels for the tracks to pass thru creating some pretty cool set ups. Definitely recommend!
