Rated 4.6 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by Exact Replacement for Expired Units. Exactly what I needed. Easy to install. Super fast delivery!!! September 22, 2015
Rated 5.0 out of 5.0 by Excellent unit, easy to install. I chose this model for a variety of reasons. It runs primarily off of AC power so if there is an incident, I did not have to worry about the alarm draining the battery and creating a hazard. It also has a battery so it is powered from two independent sources, which is what I like for a safety device. The devices all interconnect with a hard line -- this guarantees communication with other Kidde devices throughout the house. I did not want radio or WiFi communications as that may not be reliable, particularly if there was a fire. I like the fact that the display shows the levels of CO and it has a peak detector. This is good since it lets me know if there is a problem developing; I don't have to wait until there is a serious problem and safety issue. I bought 4 of the units and they all installed without issues. February 18, 2014
Rated 5.0 out of 5.0 by Safety First This is the same carbon monoxide model I original had installed. It lasted 12 years and always worked. It was simple to replace and came with a 9 Volt battery. December 23, 2014
Rated 5.0 out of 5.0 by Great product This alarm is completely compatible with the hardware from the older version of the same model. This made installation a breeze. Works great and looks great too. September 24, 2013
Rated 5.0 out of 5.0 by Fit like a glove The carbon monoxide alarm was done in my condo. I was told I could get an exact replacement on Home Depot .com. Sure enough it was a perfect fit. Just connect the plugs and no painting needed it fit the old unit perfectly. Didn't even have to change back plate. Thanks Home Depot! April 7, 2015
Rated 4.0 out of 5.0 by Works well. Had to wire in another harness, but it went in smoothly, and have had no problems. Works well with the older smoke detectors that I have now. I like the led display, and it is easier to change batteries out than on the old detector. April 7, 2015
Rated 3.0 out of 5.0 by Died early The detector worked as advertised except that it was supposed to die (stop working and go into beeping mode) 7 years after it was first powered. It stopped working and went into the beeping mode only 4 1/2 years after it was manufactured (and less after installed). I did replace it with the same model which now says it will last 10 years. I do not expect to be in this house for another 10 years so I will never know. March 3, 2015
Rated 5.0 out of 5.0 by digital CO alarm digital shows reading before it becomes deadly. great feature. also 120 and battery a must have. March 12, 2015
