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.
A well made well packaged product. My reason for only 3 stars is it looks in the picture like it holds the board almost flush with the wall. However the reality is that the board sits at about a 20-30 angle and so sits out more than I wanted.
