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 analyzes reviews to verify trustworthiness.
Was there even an editor for this? There are typos and grammatical errors all over the place. This seems to be a knockoff product that is simply riding on the coattails of a magnificent best-seller. Wish I had done more research before I purchased.
