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 material is very soft but maybe that's just my expectation from the photos. That's 1 star lost. The other lost star is probably half my fault. The description clearly states 10 pieces but I didn't notice it, instead, I noticed the image that states 18 pieces so I was disappointed when I got the package. I would attribute that to false advertising, they need to change the image to show the product they're selling. I would buy this product again though.
