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.
This lovely sign arrived very on time. Kudos to Amazon Prime. The sign is very easy to hang up. I also like it so much that you can re-arrange the space between each alphabet if you happen to have a bigger backdrop. Color is on point which is another plus.
