CZU Home Door Lock Security, Upgraded Safety Childproof Door Reinforcement Lock Latch (2-Pack), Extra Defend Door Lock for Inward Swinging Door

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

I have had these locks on double doors for a couple of years now. They are still fantastic and every time I unlock them I think about how happy I am that I got them. Easy to install, VERY secure, even for double doors!!! I would say they are the only way to go with double doors! I highly recommend these.

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.

Nice and sturdy, but I could not use it in my specific case. It appeared to be sturdy and the installation was the same as the other similar products. Once installed correctly it would be secure, but unfortunately it wasn't;t going to work in my specific case. This is a great product for protection from somebody trying to break into your residence/business. It is not so great when you are trying to prevent a person (child or at risk adult) from leaving the premises.

But I work nights, so at least I can make them get up and let me in! Easy to install, look nice, and Definitly work well.

I like the overall quality of them, but the set screws moved while installed causing it to not slide any longer making me to have to buy stubby Allen Wrenches to jimmy in there and adjust them (I would rather not remove them as that would compromise the security of the initial wood screw installation). I wish you would have mentioned something like this being a problem, that way I could have loctited the set screws.

Compact yet strong as F! Brings peace of mind.

Most of the negative reviews for this product are because the purchaser either did not read the description or other reviews or is just too lazy to install correctly. This product requires some tools and time to mortise into your doorframe. But once properly installed, they work well and I put two on each door for added security. If you don't have some basic carpentry skills then be prepared to hire someone to install these correctly. My only complaint is the color . . They need to come in white so they blend in with most trim and door frames. The red rubber pad is just plain ugly but is functional.
