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 analyses reviews to verify trustworthiness.
We bought this and kept it with us because we know many times we have to find a gift for someone's birthday invitation and we don't get time to go and find something so this came in very handy when we really needed it.
