Rated 2.0 out of 5.0 by so so purchase I bought two of these units. they plug into a wall but have a 9 volt battery in side for backup. You have to pull out a tab to connect the nine volt. One unit I plugged into the wall, 12 feet from my stove and I believe it is working. The other one I plugged into 4 outlets through out the house and it was always going off , even in a bathroom witht the window open. I unplugged it and set it on my pool table and it still kept going off until I unplugged the 9 volt battery. I am returning it and hoping the next one works June 30, 2015
