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.
Product arrived today. Seems OK. The attachment is velcro and along a thin strip on the brim so shouldn't get too sweaty on the kids forehead (unlike other hat we had). My kids are 6 and 4 and hats just big enough. Won't be suitable for older children.
