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 wanted this product for my dog to get in and out of my suv car easily without me having to pick her up every time. When I received it and took it out of box, the left screw insert for the arm to open and lock was already broken!! Very angry as product certainly was not cheap. What am I to do now as I am sick and don’t have the energy or strength to keep picking her up??? Otherwise it would have been good if it was made better!
