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.
Don’t buy it! 这是三无产品 The package without any detail of the manufacturing and the brand. Also the masks smell weird. The masks were sent from China, so I think everything makes sense. It is obviously that Chinese sellers are UNRELIABLE.
Do not buy this product ...the quality is the worse I've ever seen ..the flimsy straps just snaps even when trying to wear them...took 45 days to arrive ...it from china so what do you expect .....do not buy this product ....waste if money
Totally a scam, it arrives 10+ days later in a cheap dirty flimsy plastic package. You CANNOT find any lable or product information and the material looks and feels just very awlful. Will report this seller.
