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.
I was a little skeptical about this product but find it to be an amazing piece of mind. It's very easy to use and works great. Even when I forgot to deadbolt my door this held it safely in place and the door could not be opened.
