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.
Was very happy initially. But after two months it stopped working. The sensor is very sporadic. We had a night where the sensor just went on for ever and emptied all the soap in our sink. This is just after the return window ended.
