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.
I wanted to buy a white ring because the siding of my house is white but they don’t sell the ring in white so I got the cover in white and it looks great on my siding against the black ring. Good price too would buy again in different colors.
