Rated 5.0 out of 5.0 by This product is easy to install. I purchased this product to replace an expired smoke detector in a family room containing a fire place. This unit was very easy to install with basic tools found in any home and has a front panel that makes battery replacement a snap. The unit is neutral color and blends in well. It does not give false alarms as many units I have owned in the past did. I highly recommend this unit. March 18, 2014
Rated 5.0 out of 5.0 by Kidde CO/Fire works perfectly! I replaced my Kidde CO/fire alarms after I had a CO problem in my apartment. Woke me up (loudly) when I was sleeping and the alarm system made sure I was safe! Excellent product. The voice alarm for which aspect is alarming is very useful since I was feeling pretty disorientated. Only good things to say about this! August 11, 2013
Rated 5.0 out of 5.0 by Fabulous product ! This product was my first choice when shopping for a replacement. The price was reasonable, the style was sleek. The color is a neutral white which blends with any wall color. Easy installation, comes with batteries and screws. The voice activation is an added feature and is an exceptional idea in emergency circumstances. I rate this product five stars! I have bought six for my entire apartment building! June 17, 2014
Rated 5.0 out of 5.0 by 7 yr lifespan, worth price mine just went out last week, after 7 years of faithful service, with no malfunctions along the way. Kiddie makes a great detector, and they have never let me down. This is a great buy, but they do have an even better model out now. This time around, I will be upgrading to the li-ion battery version with a 10 year lifespan ... that's three extra years of expected life, and no batteries to change, plus you get to keep all the same features. And at about $10-$15 more than the standard AAA version, the "higher" price really just buys all those AAA's that you won't need to install... saving you time, and putting less batteries in a landfill!!

Rated 5.0 out of 5.0 by great product Put one of these units in 5 years ago. Last month the carbon monoxide alarm went off. Called the gas company they came and couldn't find a problem, suggested the alarm was bad. So I bought a new one. That one went off too and after they returned again they found the the heat exchanger on my furnace was cracked and putting co2 into the house. So the sensor saved my family. If you don't have one in your house, get one. January 14, 2014
Rated 5.0 out of 5.0 by Best purchase ever! These blinds look really expensive because they are of extremely good quality. The maintenance person in my building took exactly one hour to install blinds for FIVE windows. Outstanding!! I must also add that these blinds add elegance to any room. They are of extremely high quality. You won't be sorry!! April 8, 2015
Rated 4.0 out of 5.0 by Works great. It was easy to install and works great. It would have been even better if it had the plug in to link it with all the other detectors in the house. I needed it primarily for carbon monoxide detection. April 6, 2015
Rated 5.0 out of 5.0 by Good Purchase! Intelligent battery operated smoke and carbon monoxide alarm with voice alert. The Intelligent battery operated combination Smoke and Carbon Monoxide Alarm was a good purchase for me. Not only do I use it in my own residence, but also in the rental next door. The price is midrange and the alarm works really well. I really like the voice/speaking that goes with the alarm itself. April 3, 2015
