So, do people who use something like this just never lock your bottom handle lock? I live in a busy city and lock both to keep my place secure. I'm not sure I would like just being able to lock the deadbolt but not the handle lock.
Home door locks are a deterrent more than anything else, so I'd opt for convenience.
I also have an RFID fob to get in my building and I need to type a code in to my elevator to get to my floor, so I'm not too worried about it.
