Far bigger than I expected. The first part of the fun is assembling the parts used to build the tracks. There are many many hours of fun in this box.

There is a nice variety of interesting pieces. It is well made. For a keen marble run enthusiast it has allowed him to create unique runs each time. Would recommend!

Gefällt uns sehr! War als Geschenk für unsere 7-jährige Tochter gedacht, im Endeffekt sind wir Erwachsene dagesessen und haben wie wild gebaut. Absolut empfehlenswert als Beschäftigung für die ganze Familie und mit diesem Set kann man viele verschiedene Versionen bauen, auch wenn man keine zusätzlichen Erweiterungen dazu kauft.

Many pieces and smaller than most marble tracks, so unsuitable for most kids under seven. But it’s a wonderful track for its functionality.

This seems to be hands down the best advanced starter set and it’s somehow currently the cheapest by a long shot. The pro accessories, specialty white tiles, and walls give it the most versatility for a starter set.
