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.
I'm writing this review after having to return the book twice. Both times the binding started coming loose around 2 weeks after receiving the book. My son is 7 and is careful with his books, so he's not being too rough on it. Simple use and reading the book causes it to wear out in a matter of weeks. I would expect a book, especially one made for children, to last longer than 2 weeks. I am hoping the other 3 that I ordered don't fall apart as well. Keep this in mind before buying this book.
