To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is truly fun! Bought this for our 4 year old. He needed help building it, but it has a window to slide open on one side, a whole side that opens on the other, the sign on the top can move up and down.... so many little details to explore and play with. A very good buy!
