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.
Thank you for the opportunity to purchase a World Cup Rugby ball. I am giving it as a Christmas gift but I am sure the recipient will love it. I was a little disappointed that the ball came deflated. I had to go out and find someone who could blow it up.
