We love the concept, me and my granddaughter, and it is something that will grow with her.
Misses "Excellent" only because a number of the components are currently out of stock and one that was supplied unfortunately broke immediately.
The customer service has, however, been good and I look forward to playing with the missing and replacement components in due course.
Her parents (who both have early years care/teaching experience) are impressed with the items and I can't wait until we move on to the cogs and the marble run.
