To calculate the overall star rating and percentage distribution by star, we do not use a simple average. Instead, our system takes into account, for example, the current rating and whether the reviewer purchased the item on Amazon. It also analyzed the reviews to verify reliability. Customer reviews, including reviews of product stars, help customers learn more about the product and decide if it`s the right product for them.
