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.
Heard great reviews on this book and was looking forward to sharing it with the grandkids. They showed little interest in the book even after I encouraged them to do high fives. Tried it on all four of them aged three to six with no success.
