Rated 4.1 out of 5 by 17 reviewers.
Rated 5.0 out of 5.0 by Good Detector What's to say about a smoke detector. It sits on the ceiling, flashes to let you know it's alive and hopefully will shriek loudly, should we have a fire. If it fails to do so, then I'll have something to say. It would be nice if it blinked a little more frequently to let you know it's working. Looking up, for a senior, can be painful, especially for a full minute. January 6, 2015
Rated 4.0 out of 5.0 by A inexpensive remedy This alarm was an easy install. Placed it in our common room with cathedral ceilings. Searched forever to find a photo and ion fire alarm. Wasn't until after I ordered this that I discovered it was a BATTERY operated NOT WIRE IN. Otherwise, the inexpensive price is safe assurance that it will go off for either detection. One thing I don't like about it, the alarm has to be removed from the fixture for the battery to be replaced. Not an easy task with our ceilings. Otherwise a good product, quick simple install, and easy testing. November 26, 2009
Rated 4.0 out of 5.0 by great features The product works well. It is loud, and somewhat sensitive, but does have a "hush" button - say, if someone forgot the cookies in the oven, and the smoke lingers even if you already opened the window. February 16, 2012
Rated 2.0 out of 5.0 by not for basements placed two in basement. CONSTANT false alarms (due to humidity perhaps). August 18, 2013
Rated 5.0 out of 5.0 by This is the type you need - Phtoelectric AND Ionization I've had this unit for three years now. It sometimes goes off when I'm lighting a fire in the fireplace, but that's what you expect, right? Otherwise, no "false" alarms. The battery is easy to replace. For exactly why you need a dual-sensor smoke alarm, see the video at Dateline - NBC News online. (Sorry, I can't post a URL.) Warning: Starts with heartbreaking story. February 28, 2014
Rated 5.0 out of 5.0 by All smoke detectors should be this good. It is a darn shame that the smoke detector industry does not manufacture all smoke detectors to detect both slow AND fast moving fires, using both the ionization and PHOTOELECTRIC technologies. I don't buy anything else, I've bought many of these models. They make a great gift for family and office and it is very important to detect the slow, smoldering fires. These should last for years. Who wouldn't want to spend the equivalent of $4 extra per year for this protection? December 5, 2012
Rated 1.0 out of 5.0 by False Alarms Own Alarms for two days and all of sudden it started alarming that there was the presecne of a fire. Look around and nothing, Went off a couple of more times by itself after I would reset it. Said no to this sensor and returned it back to homedepot. Homdepot only had one manufacture as a resource which is Kidde, so I got an ionization smoke alarm model i970, and have own it for a month now and no false alarm. July 2, 2012
Rated 4.0 out of 5.0 by The smoke alarm Its good so far , pretty assuring that the product will help protect me and my family... December 6, 2011
