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 a kid, this was the first perfume I ever bought in my life. I loved it and used it like mad as a kid. I went through 10s of bottles of CK One. Decades later, in present time, during the super sale days on Amazon I found this product so I thought why not, let’s reminisce....what a failure!!! I don’t know if the product was counterfeit or has the fragrance formulation changed over the years which is normal in the perfume industry, so I thought maybe this was the same too. But why I felt it was fake was because while all my perfumes arrived in boxes wrapped in cello (clear plastic) wrap, this was the only one that came unwrapped. Unfortunately I have no way of verifying it’s authenticity so I have kept it, the guest toilet next to the sink as a hand fragrance.
