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.
For some reason when someone push the doorbell it's not ringing. I've got to call the technician to come back to see if there's a defect. If unable to ring I will contact you for an exchange. Let me add when the box was delivered it wasn't in a protector box not was it taped up and it was raining. Like they grab the box stuck address label and shipped.
