What owners single out
Buyers' weakest aspect—piece variety & set completeness—directly mirrors video reviewers' concern that the starter set runs out of pieces quickly and requires expansion sets.
In their words
“I bought this starter set for my 6-year-old son, and it has been a big hit. The pieces are sturdy and fit together well, making it easy for him to build different tracks. He loves experimenting with how the marbles roll, and it's fun to see him learn about speed and gravity while playing.”

“Ostin Gravitrax-radan syntymäpäivälahjaksi pojalleni, ja se oli loistava valinta. Hän innostui siitä heti ja vietti tuntikausia rakentaen ja kokeillen erilaisia ratoja. Se on hauska ja luova peli, joka kehittää myös ongelmanratkaisutaitoja. Laatu on hyvä, ja se on mukava yhteinen tekeminen meille. Ainoa miinus on, että aloituspaketti voi ajan myötä tuntua hieman rajalliselta, joten lisäosia saatta”
