Combine these with the metal door armor strips and it's hard to kick in. This just screwed into a door frame would not offer much protection

They offer way more protection than a chain bolt lock and more than most deadbolt plates, with only two short screws, secured to a wooden frame. Use 3-4" screws that go through the wooden frame into the king studs, or use self-drilling screws with a metal frame.

Decided to buy one until I found out it needs tight, rigid physical tolerances between the door and the frame. It does not work well in California due to slight shifts in the door frame caused by earthquakes. But if you live elsewhere, this type of lock seems to work well; remember to use 3" screws instead of the included ones.

bought these to keep a sleepwalking toddler from wandering out of the house. They are easy to mount up and out of arms reach.

I've seen these can be easily bypassed with a milk gallon plastic or hard plastic type of thing. But I'm guessing these are good for an extra layer of defense against crackheads who are breaking in without much thought or concern. I think a lot of the people online who obsess over absolute security do not realize that the average break in is not done by intelligent criminals. Those people will get in no matter what kind of defense you have in place and they are also smart enough to avoid places with cameras and a decent level of security. They also scout out places and plan accordingly so yes, something like this is pointless for those people, but they often also don't target randomly and places that have cameras, security alarms, etc. It's the drugged up junkie who is completely out of it and low IQ to begin with that this thing comes in handy for and those guys are dumb enough to go into any house when drugged up and paranoid.
