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.
When I received the product I was so satisfied that its a worth deal and and also wrote a review that can misguide others. Now I am writing this review after a wash. It was totally waste of money. Its Rayon not Cotton. Product description is totally a misguide.
