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.
The quality of the product is quite disappointing. The locks are not really well made. The board is made of compressed chips board. Bits of the chip wood can be found where the screws are. Don’t really recommend this toy.
