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.
Now that I’ve had this for a while, (several months) all I can say is sometimes it works and sometimes it doesn’t.

I may stop using it because it’s possesed! 😳😱😱
