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.
Delivered on time, product as described. Would have been 5 stars had the balls been inflated. Need inflated before I can comment that they are not leaking air. Packaging was big enough to allow them to have been inflated.
