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.
Excellent for leather boots, but this twin pack is very expensive. I thought the free gift, the orange bag, would have cloths, shoe brush etc, but no. It's just an empty pouch for the two tins! I could have bought just two tins for half the price.
