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.
Great product! The actual thomas image on the top is a part of the fabric (not a rubber image sticked to the fabric) so no matter how many times it's washed it lookes the same. Fitts my 3 and half years son.
