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.
It was easy to install and adds a shelf's. My only complaint is - Our 2020 RAV4 has a courtesy (blue) light to help see the shelf at night. Installing as is the light is lost. I drilled a round hole in the top and a square opening on the bottom (about 1 1/2 sq) to let the light come through. This lets both shelfs be lite. Also cut a opening in the mat.
