Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I purchased these air hockey replacement pieces for a recent purchase of a used air hockey table. They arrived quickly, were just as pictured and described, and seem to be of good weight and quality. I am very pleased with this purchase.
