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.
It's just a scraper right? Well after a month or so use it's become my favourite kitchen utensil. Originally purchased for making bread I've found it rugged and has multiple uses. The measurements are clear and useful when recipes call for lengths of dough etc. I wouldn't put it in the dishwasher because I like to retain the nice wood finish but it would probably stand up to it. Amazing value
