First Alert Combo Smoke/CO Detector is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Excellent This product was installed in my apartment by the Landlords handyman. It's much more compact then the separate detectors I previously had. It was easy to install, compact and is working very well.

Rated 5 out of 5 by from Dependable Reputation This combination model was added to work with my existing Co2 units and three new replacement smoke detectors. First Alert has the reputation for dependability, like all equipment of this nature it is hoped that it never has to actually do its job, but if it does, you want equipment with a good reputation.
