I've slept with one of these forever. I can't sleep without one unless I'm somewhere where I can't hear traffic or neighbors. For some reason if I hear other people up when I'm trying to sleep it keeps me awake. They travel well too - I'm in Nashville for work all week and have mine in the bedroom. It helps cover the idiots banging around upstairs at 4am. The problem is my wife is addicted too now so she has one at home.
Your dogs will wake you up if someone comes in.
Also, like someone above said, keep your bedroom door locked. A buddy of mine used to work security in South Africa during the border wars and said most of the time when "simians" came to "get you" the victims only woke up when one is straddling your wife and the other has an AKM to your head. Locked bedroom doors are the best alarm possible. If someone forces through your locked door there is no question that they need to be shot. Flashlights be damned.
