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.
Should have been a simple installation, but the included screws were too brittle. I hand tightened every screw, but 3 broke off at the head. Would advise using better screws. Would give 5 stars if they didn’t cheapen out on the things required to secure the lock to the jamb!
