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.
The book arrived very dirty. Normally I like this book very much and like to give it away as a baby gift. However; the book arrived in such poor condition that I cannot give it to anyone. Very disappointing.
