U.S. Patrol Keep Closed for Maximum Lock

My mother-in-law just recently started obsessing about the sliding glass door. Saying it wouldn't lock... (even though it did.) And worry unnecessarily about someone breaking in to the house from our backyard. She started putting chairs in front of the back door at night, which wouldn't prevent anyone from coming into the house and would only cause issues if we had to hurry and get out in case of a fire. Originally I was just going to buy a wooden stick to put in the door but I searched and found this on here. It's perfect. I know a few reviews stated it didn't fit perfectly to their door's dimensions but even if the door can be cracked open an inch or two... that doesn't take away from the fact that the door won't budge from that point. Mine fit in perfectly, I had to fix the screw into a different hole but it fits snug and the sliding glass door doesn't even move if this is put in place properly. I also like the fact that it looks nice and is easy to get out from the door. With a bar sometimes that sucker rolls or you pinch your fingers trying to pry it out from the door.
