Review: Keeps your loved one safe - These locks are amazing. I take care of my aunt with alzheimers she wanders all day and night. I will have the aides put these on at night to front and back door and she can't get out. She's attempted to pull off and pry off with tools and they don't break. This allows the aides to get some rest without the worry that she is going to get out of the door and wander into street. They have met all expectations and more. They are very well made!!!
Review: It's an excellent product - Excellent

### ⭐⭐⭐⭐⭐ Security
*by S***H on 24 December 2024*

Works well and would deter break ins. It helped me keep put a maintenence who was actively waiting for me to leave my apartment after giving me different dates and times and decided to try to come in when I said I had an errand that had to be ran at a certain time in which he chose to try to come in at that time. (I prefer not to have him alone in my house as he doesn't do his job and went through my soaps under the sink wasted a roll of tp and used half a bottle of my handsoap then proceeded to tell me it's his job to do that and be on Facebook without just leaving when he was done) I would recommend getting as this really does help
