Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
As the title states, I am extremely happy with my purchase! Not only did the product fit the description....and me... it was delivered before the 'due date" Great price and product. I will be ordering again. Thank you :)
