    No instructions included.  Not an easy install.
  

*by B***N on Reviewed in the United States on March 22, 2020*

First off, the product works when installed.  That is fine.  No instructions meant that I had to figure out how to install this lock.  I have curved molding next to my door.  I had to cut into it to create a deep, flat surface for the chain assembly to sit.  Then I had to arrange the lock in a manner so it would lock easily.  After some trial and error, I finally got both sides installed.  As stated, it works.  The screws are almost too short to hold in a hollow door.
