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.
Efficient and quick shipping. Happy with the hutch. The size of the opening on the top floor for the ramp is more designed to accomodate rabbits than for guinea pigs. A little bit of craftwork reduced the gapping hole and providing more floor area on the top floor. The only issue was the instruction sheet which requires a lot of guesswork; it took a lot of thinking and trial and error to put all the pieces together right.
