### ⭐⭐⭐⭐⭐ Review
*by H***A on 13 October 2022*

Als wir gesehen haben dass es neue Erweiterungen gibt haben wir uns direkt den Hammerschlag und die Rutsche bestellt. Zuerst was zur Lieferung. Leider kam die Bestellung in einer Amazon Tüte wodurch die Verpackung nicht mehr ganz die neuste war. Aber da wir das ganze eh selber behalten ist es nicht weiter schlimm und dem Inhalt hat es nicht geschadet. Wie ich es von Hubelino schon kenne, sind auch diese Erweiterungen in einer Top Qualität. Dafür dass wirklich alles im Gegensatz zu den bekannten Marken in Deutschland geschieht finde ich auch den Preis vollkommen angemessen. Der Hammerschlag passt perfekt zu der schon bestehenden Kugelbahn und den verschiedenen Erweiterungen. Auch unsere kleinste (3 Jahre) kann Ihn ohne Probleme nutzen. Mal wieder eine nette und kreative Idee. Es macht wirklich Spaß das Ganze mit meinen Kindern immer weiter aufzubauen. So wird es für uns nie langweilig damit zu spielen.
