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 have had acPaddington bear for about 30yrs sadly I lost the tag. I have been looking for a tag for a long time. Very pleased really nice it may have taken me a long time to replace the tag but it was well worth it was also a good price.
