      I was just buying a few more detectors for our NEW home, after a serious fire in 2010 badly damaged our little cabin. A combination of the breaking glass and the smoke detector woke me up at 12:30 a.m. to find our home ablaze from a broken porch light (my review of THAT product is very poor!). Thank God it woke me up and it also scared all of our pets safely out the doggie door, too. I was able to turn on a nearby water hose and battle the fire until help arrived. It wasn't a total loss, thanks to these wonderful detectors, that also detect CO2, as well.
