Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
This was a great buy. It had more dinosaurs than I had anticipated and gives good, clear illustrations of each. Most are a little more advanced than the cover illustration, so depending on how skilled your artist is, this is a good buy for both beginners and intermediate artists.
