Nonetheless, the screws are below average and they tend to break when being screwed-in in the 3/32 hole drilled as per its instructions. This can be resolved by using higher quality screws.

Rated 5 out of 5 by from GREAT PRODUCT This is a good lock, easy to install and use. I had seen it in a hotel and knew I needed one because it was so much easier to use than the stick I was using to block my doors

Rated 5 out of 5 by from It's a lock It's a lock and does what I need. I placed this lock on a patio door I couldn't secure otherwise. Does what it's designed to do. One change, I didn't use the included screws for mounting to the door jamb. I used 3" strikers (drywall screws) to connect the lock to the studs.

Rated 5 out of 5 by from Works well I'm using the lock on a rear sunroom door not a sliding door but it works. My wife wanted me to paint the first one I bought but that made it too thick to work right so the second one won't be painted. For the price, it can't be beat.
