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.
Really like the quality of this unit and battery life in particular. Works like a normal doorbell except that it records it all. A few fals notifications but I can live with that. Problem for me is that when I am not home to hear the doorbell, most people tend to have left by the time I get a notification on my phone to respond. At least I can usually see who it was though.
