Just to counter his anecdote, I'll give mine. I have two hard wired Protects, since they were launched. They've gone into their low threshold alarm modes twice from cooking, and both times I've had my kids silence them. They know how to "go wave at the alarm" because they're around when I test it (monthly) and I tell them about it. I've never had any unusual behavior, I look out for the green "everything's okay" response every night when I turn off the lights, and I've been very happy with the Nest Protect.
