Misleading name and misleading description, the "Balls and Spinner" accessory does not have any balls. It's just the spinner.

Kids enjoyed it. They like having the add-ons. I like that it gets them re-engage in an older toy.

Wem der normale 3-fach-Starter nicht reicht, der nimmt halt hier diesen 6-fach-Starter, ermöglicht richtig komplexe Bahnlandschaften.

Works great to launch multiple marbles. Important to know that this is a manual accessory that replaces the traditional three marble push starter.

A scuola, dove lo uso, i miei bambini avevano perso le biglie. Le ho trovate e la confezione contiene anche una piccola stazione da aggiungere alla pista che alla fine è costata meno che prendere solo le singole biglie. Ne sono molto felice
