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.
This is the best quality and has 2 pots for steaming in multi cooker.Have had a previous cheaper one and last two weeks. Take frozen veg and steam in 5 minutes. These baskets fit on top of one another so you can have say fish in the small er one and veg in the big one. Very impressed with service delivery.
