    This CO monitor replaced an aging OneLink smoke/CO combo unit. Placed in a hall unwittingly close to a bathroom, the old unit was prone to steam-induced false alarms. Obviously, a CO alarm isn’t. Existing smoke detectors in adjoining bedrooms pick up the slack in detection. The new unit connected properly to the other OneLink units in the house, so I’m happy. I hope I never get the true positive detection warning that would merit a 5 star rating.

    Having used OneLink units for about 7 years (and now starting on my second generation of them), yes, I do recommend them. I would caution users to keep the smoke alarms clean by vacuuming them out, because they can give false detections otherwise. And with a house full of beeping alarms, all chattering slightly out of sync, false alarms are especially annoying. However, with 7 alarms spread across 4 levels, from basement to attic, OneLink w/ Voice is really the only option.

    Worked as expected and tied into the other First Alert devices and the bridge to my home automation system.

    I bought this carbon monoxide detector because it was a top rated carbon monoxide detector by Consumers Reports, and buying from Amazon I got the best price. You can’t go wrong!
