Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
When package arrived I counted the sheets - there were only 36. They contain vegetable oil which I prefer - but there is hardly any in the sheets so I don't think it covers all the blades when using it. Very disappointing - I guess you get what you pay for and it's better to order the more expensive sheets to get what you want - something that works.
