CUSTOMER REVIEWS

Rated 4.5 out of 5 by 78 reviewers.
Rated 5.0 out of 5.0 by Simple to install! Easy to install, 5 year warranty, voice messaging alarm and comes with starter batteries. Great features and was slightly cheaper in-store! June 7, 2008
Rated 4.0 out of 5.0 by Alarm that Works This smoke alarm works well. It is easy to install and will give you an audible warning when the batteries are running low. November 12, 2008
Rated 5.0 out of 5.0 by This alarm has voice alert which tells you what kind of danger is present. This combo alarm protects your family from both fire and CO poisoning. Voice alert, in addition to alarm beeps, tells you what kind of danger is present. It's very important when you have short time for action. Battery operation makes installation easy: you don't have to do wiring connections. April 30, 2014
Rated 5.0 out of 5.0 by Saved My Life and Property! 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. September 24, 2013
Rated 5.0 out of 5.0 by Worked in a CO emergency We purchased two of these when we bought our house. Our heat exchanger in the furnace went and at 1:30 AM we were awaken by the detector in my baby's room "beep beep beep Carbon Monoxide!" At first I thought it was a fluke because nothing seemed to be wrong, so I reset the detector and went back to bed. One minute later the detector went off again. Then I knew something was very wrong. When the firefighters arrived they said without these detectors, me, my husband and my two sons (16 months and 10 weeks) would have died. I would recommend this detector a million times over. My family owes their life to this detector. March 20, 2007
Rated 5.0 out of 5.0 by Excellent Product This smoke and carbon dioxide detector provides protection from two potentially deadly threats, fire and carbon dioxide poisoning. It was a great value and very easy to install. The built in voice feature speaks clearly "Fire! Fire!" Along with a very shrill alarm tone anytime there is smoke present. It also verbally warns of CO and sounds the alarm tone. I was so impressed with this detector that I went back to Home Depot and bought three more to protect my family. I highly recommend this product. December 30, 2014
Rated 3.0 out of 5.0 by Not worth it! Ordered 2 online, and only 1 worked. Returned the defective one to store for credit, but do not plan to order another. I will buy one in the store and pay a little more for it. June 16, 2015
Rated 3.0 out of 5.0 by Talking Smoke/CO Detector - Doesn't Rap. I bought this for a rental, so I wanted the tenant to be able to easily differentiate smoke from CO without consulting the manual. The voice is so quiet compared to the ear-blasting squeal of the alarm that it's almost useless. Just meh. June 4, 2015
