Title: Works great!
Review: I installed two of these to replace two 15 year old alarms when I purchased my house. The original batteries have lasted 15 months and still counting, (not sure what everyone else is complaining about) Mine has never went off so maybe others eat batteries because they are set off occasionly?This smoke alarm offers ionization sensing. Here are the two types and definitions of each (From Kidde website).Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than Photoelectric alarms.Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than Ionization alarms.Studies show both types will effectively detect either type of fire.
