Video and written instructions were straight forward, but I had some difficulty getting the dead bolt to engage properly into the jamb shield during installation. There was a bit of trial and error involved. All doors are not created equal, so be patient.
For my installation, positioning the jamb shield as far as it could go behind the rubberized would not work. Instead, the jamb shield lip had to hang a bit over the inside frame to get everything true and deadbolt engaged.
Hinge shields went on very easy.
Lastly, the door shields always seem to be left-overs in the videos. However, I found them useful to use on other doors, specifically on entrance doors into my house from the garage. So, don't store and trash them. Even if left over, they may have a good use.
