Title: Works great, landlord didn't even notice I changed smoke detectors
Review: I bought one of these because it was easier than getting the landlord in to replace a defective smoke detector. It plugged directly into the old wiring, but the mounting ring was a slightly different size than the old smoke detector. Not a big deal, it still only took me five minutes to install. This communicates with the others in the house, just like the old one (i.e., when one signals smoke, they all do).Note that this one does not have a battery, so you must have house power to it. I'm not saying that's bad or good, it just depends on what you need (in my case, I was happy to not have to worry about a battery).
