Rated 4.6 out of 5 by 13 reviewers.
Rated 5 out of 5 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 out of 5 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 out of 5 by 2nd Purchase I bought 2 of these seven years ago. Just replaced with 2 new units as planned life expectancy was 7 years but now up to 10 years. Reliable, no false alarms and digital readout gives me real peace of mind. Easy to install. When they do fail it is almost exactly to the date of seven years. Internal timer exact within 5 days. It is a good reminder to replace units with fresh sensors. May 6, 2014

Rated 5 out of 5 by Simple to Install I am a 60-year old single woman. I was able to install the alarm without help in about 10 minutes. Definitely recommend this product. July 29, 2014
