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.
Awesome enclosure! My two bunnies love it, the only thing I would change is to have the roof on hinges to be able to get in from the top but that's a personal preference. Quality and price are great and SUPER quick delivery!! Very happy!
