I'm getting really frustrated with my smoke detectors. Kidde detectors have gone from being great to busting in two years of ownership. I can't have them in my house if they are going off randomly at 3am in the morning for no reason. I can understand if it is an environmental issue that causes the problem. (My wife won't turn on the exhaust fan over the stove so every time the downstairs smoke detector goes off, I've got the kids trained to yell "dinners ready!") But random beeping and alarms just won't do. I'm about to pick up some more detectors for the house. (Two have failed at the same time.) Any suggestions as to a brand that has some quality left in it?
