### ⭐⭐⭐⭐⭐ One of the best door locks
*by S***R on January 25, 2026*

one of the best door locks ever! easy to install easy to use Super strong, don't let the size sway you away!

### ⭐⭐⭐⭐⭐ Keeps kids out during fun nighttime romps
*by T***O on January 4, 2026*

Works great

### ⭐⭐⭐⭐ Fantastic extra layer of security for peace of mind! Highly Recommend!.
*by U***C on November 6, 2016*

We bought several of these for our entry doors. They are easy to install and do a fantastic job of keeping the entry doors closed even with the weight of a grown man pushing against it from outside. One is sufficient on an entry door and does the job it is intended for. We used two to add more security. Another plus is that if you need to go in and out of your door and want to keep it from closing, just flip these over in the door. Looking for an inexpensive, extra layer of security? These will work just like you hope they will. Only caveat is that these only work when you are at home. NOTE: Some are easy to flip back and forth without any concern. Some, when new are quite stiff and takes some working at to get them to flip open and closed when using. The screws that come with them aren't worth anything. Get better sturdier screws.
