Our AssessmentAt Amazon.com, many carbon monoxide detectors have several hundred owner-reviews and earn high average ratings, including the Kidde KN-COSM-B and the First Alert CO615. The site is a good place to start to get a pulse on the product's best features as well as reoccurring problems that owners most often run into. For example, the First Alert CO615 is extolled for its effectiveness, but criticized for its poorly made battery cover. The First Alert CO-400 is praised for its easy installation, but a few lemon units got complaints. And, about 63 percent of owners gave the Kidde KN-COSM-1B, a hardwired unit, a perfect score for its reliability and easy installation.
