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.
I feel bad saying anything negative as I spent less than $3 on this and they were shipped from the US to Australia for that but the cat hasnt been even remotely interested in them! Not sure if the catnip fell out in the Pacific but the cat hasn't even looked at them! Plus they were delivered to the wrong address. In the wrong street. In the wrong suburb!
