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.
First off this isn't what I wanted. I was told that what I wanted wasn't available anymore and that this would work, I need PVC Printer Double sided cleaning cards, these cards actually go through the printer and clean the transport rollers and printer heads and magnetic head. I was sent cleaning cards but they are just to clean card readers, I can use them or give them to my customers to clean there readers. But not what I needed.
