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.
It’s toothpaste. Average only. Not as good as Colgate total mint-strip! Also the top is not big flat to make it stand upside down. I just bought it as this was available on prime deal. You do have to buy 5 at a time so I’m stuck for sometime!
