Review: Perfect!! - Easy to install, very secure! Need a lock for my bedroom and with a uneven door frame this was the perfect choice.
Review: Works extremely well - Purchased to keep the kids out of our bedroom when, well, you know what might be happening... Replaced the screws per other reviews which advised to go with a better set. The door lock looks appealing and is very sturdy. I just wish it had a little better advice on positioning as it's hard not to install with too much wiggle (ie. door opens a little before stopping). Also installed a second set on the family bathroom. A clear advantage of the product is that one cannot lock by accident from outside. However, it would be impossible to override it if the person becomes incapacitated. So maybe not ideal for older people.

## Features
