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.
Got this for $15 and its got a great fresh smell to it. I couldn't believe how cheap it was and the great thing about it, it lasts for quite a while before you can't smell it anymore. Not like some other brands the smell sticks around in a good way!
