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 analyses reviews to verify trustworthiness.
Three days after purchasing this product I got a call from the Michelin Guide, telling me that my kitchen had been awarded 2 stars. I replied that I didn't even own a restaurant, to which they said that they didn't care. Now I have to make a reservation to dine in my own house. Outrageous.
