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.
If I remember correctly this order arrived within a week or under, very fast!! The case is awesome, although the foaming parts inside could be a bit better quality but not complaining!! Happy with my purchase, can’t wait to use it!
