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.
I am happy with this purchase. I bought the medium navy headband, the fabric is cotton and very soft. I tried using it as a face-mask but it does not stay put very well, probably because I have a smaller head. Otherwise, definitely recommend and I would repurchase. Thank you.
