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.
We have quite a few of the Amazing Machines books. My toddlers favorites are the Airplane one and the Rocket one...both of those are on the shorter side. While we enjoy this book it is a little longer than the rest and sometimes my toddler is a little less likely to listen to the entire story. Definitely not an instant hit like the Rocket one.
