Works great. A must as lots of fires start in a garage. ### ⭐⭐⭐⭐⭐ This is a good, dependable product *by on Reviewed in the United States 31 July 2026* This is a good product, easy to install works as a stand alone unit or connected to a combination of Kidde smoke/carbon monoxide detectors or Kidde heat detectors. The only thing that was unusual was that when I pulled the yellow vinyl strip out to activate the battery I did not realize there was more to it. The heat detectors chirped about once every sixty seconds. The problem was that Kidde installs the battery backwards so the unit is not activated even after the yellow strip is pulled out. Make sure the battery is turned around so the battery terminals face the unit's terminals. ### ⭐⭐⭐⭐⭐ Great for area where you cook *by on Reviewed in Canada 5 September 2020* Works great in an area where we cook all the time and the other “smoke detector “ was constantly going off.
