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.
The product is lovely. A bit smaller than i thought but works fine. Only problem was that it was a bit squashed and damaged on bottom when it arrived. There was no protective box or anything and was slightly squashed and damaged in post.
