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.
Pears soap is brilliant & my favourite as I have been useing it for at least 40 years. Scent is also marvellous. Only drawback is is melt down a bit quickly than some other brands . Still taking into other factors it is worthy to purchase & rated 4* for value for money.
