### ⭐⭐⭐⭐⭐ Solid Look, Easy To Install
*by T***� on November 24, 2025*

Very solid easy to install lock. Heavy duty this was easy to install, it fit the doorframe perfectly and it functions as it should. Great lock, great price!

### ⭐⭐⭐⭐⭐ Easy to install
*by A***E on December 31, 2025*

Awesome lock! I feel so safe.

### ⭐⭐⭐⭐⭐ Good but better suited for utility room than front door
*by M***L on June 5, 2024*

Replaced one just like it that was at least 15 year old. Using it on a very old and lightweight door that‘s too thin to take a deadbolt assembly. This is a reliably built, jimmy-proof surface lock. I don’t believe it’s as stout as a deadbolt. But it does a fine job on a door that anyone could easily blow through regardless of which lock was on the door. Probably better suited for a utility room than the front door of your house.
