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.
When I tried to file a claim after one year of use, they just said that I need to contact the manufacturer since they cover very specific mechanical failures. I don't see the point of buying this claim. They don't say anything about the sort of mechanical failures they cover before purchasing the claim.
