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.
The good things about this product is that it was SUPER easy to install and, for the first few days, I felt safe at home when the lock was engaged. However, I have now had it...less than a week? Possibly two weeks. And it no longer works in the least. Even when engaged, the slightest pressure to open the door causes the lock to swing open and thus renders it void. Very disappointed in this product, especially since it worked so well at the beginning.
My husband has Alzheimer's and prows around at night, turning on lights and otherwise disturbing my sleep. To keep him safe and to give him as much freedom as possible, we put this type of lock on outside doors, except for the bedroom's patio door which he can open in case of fire and get out into the large back yard which is also enclosed. Therefore when I wanted to sleep in a separate room I wanted a lock on my door to keep him out. Instead of getting the same brand, I bought this one in order to get it in white. I was never as happy with it as with the others, because if I did not really check that the door was locked, it would open anyway. Then the rubber closer started to pull out of the groove, and now it is almost impossible to lock! I am now ordering a new lock from the previous company. The concept is good; my husband has not been able to figure out how to open the locks, and, in fact they are not easy to open for those of us who know what to do.
This is an imitation of the Defender Security Door Reinforcement Lock and does not include 3 inch screws that are necessary to strengthen the lock. Screws can be purchased from a local hardware store but they should have been included as the lock is ineffective with the included screws.
