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.
Very nice, feels like great quality comb I purchased to use on my 2 standard labradoodles. This is a pretty large comb, comfortable to hold my hand to use for dogs after I got the hang of it (took about 2 minutes) and worked very well for getting a few knots out. The quality of this feels like a professional grooming tool!
