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.
Fantastic lunch box. Was very worried about buying it off here as I like to see the item first. But having a shark loving son this was the only place I could get one and it's perfect. My son can't wait to use his shark lunch box when he starts school September.
