OUR TAKE
This detector doesn’t have a digital display like some of the others, but it does have two indicator lights that flash when it detects smoke or carbon monoxide.
PROS
-Continues to work even if there’s a power outage because it’s battery-operated
-Uses an electrochemical sensor for carbon monoxide and a photoelectric sensor for smoke
-Has three types of beeps—one for detection, one for low battery, and one for end of life
CONS
-Doesn’t ship to New York residents
-Some customers received defective ones that died within a few months
