Amazon calculates a product's star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers and factors that establish reviewer trustworthiness.
The product delivered is no wear close to the picture shown. The quality is aweful. I ordered cotton and got some worst quality and that to these mask fit for kids below 3 yrs...its that small and don't fit adults as described by the seller/amazon. This is the third time I ordered a mask and all three times received worst product. And over that there is no refund policy nor replacement allowed.
It's very bad..it's not valur for money, not comfortable and material quality also very bad. I never expected this from amazon.very bad experience and the other thing is not returnable too..so I lost my money
