Lock works great easy install
Great lock. Have a severely autistic child in the house and cannot unlock it. Keeps her safe. I have them on multiple doors

Super easy to install and use!!
This was super simple to install. I didn’t even have to drill pilot holes. It took me about two minutes total to install it. It seems very sturdy and well made. The entrance to our upstairs bonus room is through our 10 year old’s bedroom, which is understandably creepy to her sometimes at night, and this makes her feel much more safe and secure. She has no problems using it. Highly recommended!!

Effective and safe!
Installed this on our front door to keep the littles in but love the security it gave me for keeping unwanted visitors out. Feels like we made our home that much more secure.

Peace of mind….
What a game changer! Arrived in perfect condition; extremely easy to install and directions barely needed but well presented; excellent quality as well. It truly is a small price to pay for increased security! I’ve already told many friends and family to purchase. Crazy to think something so light weight can withstand 800 pounds of force - but just try to even open the door when this is locked in place!! Bravo!

Strong & Reliable Door Lock Reinforcement!
This door lock reinforcement adds an extra layer of security and peace of mind. It’s made of durable, high-quality material and is easy to install with just a few screws. Once in place, it provides a sturdy defense against forced entry, making doors feel much more secure. A must-have for home safety! Easy to install even if your door has a gap between itself

I’ve used three of these in our house
I recently wanted to reinforce our double entry front door so I placed one of these on the top of the stationary side of our doors after reading another persons review stating that this was a good idea. It has greatly added to the strength of our door should someone try to kick it in. With this at the top, my new brace I just installed in the middle and the kick plate at the bottom I’ve greatly strengthened our front door. With home invasions on the rise I really wanted to do all I could to reinforce our door and I think it’s helped a lot. I also have one of these locks on our door going from the garage to our laundry room and I just installed one on our master bedroom door. These are great locks and they give you an extra layer of security should you need it.

Simple, effective protection
I (62F) have installed these on doors in several apartments and my home. Allows a door to be quickly secured from the inside, but opened fast in an emergency. I have a door going to the basement with outside access that was a weak spot in our security - no more. The bronze is great against a wood door.
