Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
I'm actually not sure how effective it is yest but the reason for the 1 star is the fact that some lazy, inattentive worker cut the sheet crooked! It was meant to hang on a wall, covered by other material and corners were not at 90 degrees. Very noticeable. I will not buy again from this co.
