To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Mask was made of cheap and thin plastic and the only stability support was a single piece of packing popcorn (yes, you read that right) glued haphazardly to the general vicinity of the forehead, but nowhere near centered or aligned. Would not purchase again, however, after reading my review of this product, the seller contacted me and did refund the price, so credit for good customer follow up and service.
