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 have purchased these in the past and loved them. Unfortunately some of the bags in my order are not sealed properly. The blue plastic on the back doesn't have a proper seal so the bag is open in the back.
