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.
This is a comic book sketch and balloon text format that someone didn't think through very well. The text is way too small to read on a 7" screen. Why this came up as an option when searching for kindle "books" is another dismal failure of the Amazon search engine. I wasted money buying this useless junk and there does not appear to be any way to undo this sale.
