Review: Got this to secure my toddler - I'm basically purchased this because I was looking for something to secure my toddler. While I was home he got outside of my front door. I looked and was quite surprised and thought I needed more protection from him trying to leave the house and also keep the aesthetic of my front door without having a chain lock. This was right on time. The ease of installation was okay which is my only knock I didn't really chip away at the wood like they recommend it because I didn't really want to damage my door frame however I did find a workaround where I moved it back a little bit further and used all the screws that were allotted in the package. You have to be careful to line this up exactly or you will have a problem closing your door which is another knock. The lock is solid quality it locks very well the other thing that I had trouble with is when you first get the lock you have to use a small allen wrench to turn two screws so the lock itself won't be so rigid and slides back and forth easily. They also provide you with a rubber pad that it hears to the door so when someone opens it it doesn't SCAR or damage your front door. When I apply these and told my toddler to open the door he struggled and could not do it also he could not reach it because the height at which I put it at which was another thing where I got my value for my money. I put one on my front door and also my back door and have had amazing results since then. So despite the few downsides of the product I still gave it five stars because overall it did a good job of keeping my toddler from going out the door without my permission because they learn to access locks really easily because their floor level great product

Just finished installing the security lock. Follow directions and you will get a good security system for your door. Very easy to use, just slide lever to left to lock and to right unlock. Easy as that. A really great product to secure your door from unwanted intruders.
