Title: a gyp
Review: I bought this carbon monoxide detector specifically because it said it plugged into the wall, and I hate fooling around with changing and testing batteries. It does say it has a "battery backup" - but what they don't tell you is that the darn thing does not work at all unless it has an active battery in it, even if it's plugged into the wall!I set mine up, plugged it in, but it does nothing unless there is a battery installed, and if the battery dies the thing goes on the blink and beeps at you until you replace it, even if plugged in. So what is the point of being able to plug it in if plugging it in does nothing? Mine is currently eating a battery and going on the blink about every three days now, so I will trash it and will not buy any more deceptive products from Kidde.
