I'm telling you man, look at the one I linked above. I mounted mine about a foot below the top of the door, and I am unable to force my way into the house with only that lock latched. It works very well, you barely notice it, easy to operate and there are no additional pieces needed for it.
I wonder how strong that is. They advertise that it is for unwanted exits from a child, they say it helps against forced entries but that was not its design. I like how you don't have the extra piece to put in though.
