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 disappointed with the quality of the book. Purchased it as a gift but the material feels cheaper, not as high quality as other coffee table books. Also the print quality isn’t as high as I expected, making the images look less impressive.
