Powered Alarm SCO5CN Combination Smoke and Carbon Monoxide Detector, Battery Operated, 1 Pack, White

Excellent alarm. It was easy to install, the alerts are loud and clear, and I appreciate having both smoke and carbon monoxide detection in one unit. It feels reliable and well-made, giving some extra peace of mind. Definitely worth the purchase

So I needed a smoke and CO2 detector that would not go off every time someone showered. The steam was setting off the old one. This one is perfect and solved the problem. Also like that it takes standard batteries.

I really like that this smoke detector includes Carbon Monoxide (CO) detection with it. The upside of this is that in replacing an old smoke detector, I now have extra protection against CO leaks. The downside of this is that this unit only lasts for approximately 7 years according to the user manual included with the unit. At roughly 7 years (which I assume is roughly as the unit does not have a precise time keeping setup), the detector will beep at your continuously until you replace it. Note that according to the user manual, you can silence this "End of Life" alarm for 2 days by pressing the button on the unit. So, you could continue using it so long as you tell it to be quiet every two days by pushing its buttons (pun intended). However, the "End of Life" alarm exists for a reason, and as many reviewers (and question answerers) on Amazon have noted, the CO detection functionality will have deteriorated such that you really need a new alarm. The quality of the unit seems good. It is made out of plastic, but seemly high quality and durable plastic. There is a mounting plate (also plastic) that you screw into a wall or ceiling and then the detector unit goes into that mounting plate and locks with a quarter turn. The test alarm sounds loud (which is a good thing for deep sleepers), and the use of AA batteries is a refreshing change. I hated buying 9V batteries just for the smoke detector. It is important to note that I did not evaluate the sensitivity of the CO detector nor experienced a smoky fire (or any fire), so this review assumes both of those listed functions would work properly. Also, I have only owned the product for ~ 1 month so I cannot comment on the reliability or lifespan of its operation. I can testify that I replaced a 30+ year old First Alert smoke detector that was (as far as I know from burning things in the kitchen) still working so I do have high confidence in their brand. I only replaced the old detector for a combination of two reasons: (1) I wanted CO detection and (2) the old one's plastic was yellowing. I think it is also important to point out (although it is well mentioned in the product page) that this detector is NOT for new-er construction homes that have interconnected smoke detectors (i.e. if your smoke detector has a plug in the ceiling that it plugs into).

Good smoke/CO detector, malfunctioned after a couple years. I called the company and given their generous warranty policy, they replaced it with the new model for free, just had to pay a few dollars for shipping.

Great brand easy to install! Be mindful of the difference between just smoke and CO and smoke detectors! Other than that, excellent purchase - better price point than local hardware stores.

Work really well, just got the FMO

A member of our family had a close call with some Co2 recently. This prompted me to get six of these first alert combo detectors. Installation is very straightforward. I now have one in every bedroom and the hallway and the kitchen. The fact that they are battery operated is a big plus. No wiring no electric electricians just two screws and you are done. I know that first alert has a stellar reputation for safety and Quality. I have already read some of the reviews of the Great customer service and warranty provide provided as well. I just installed them so I can’t give you long-term reviews, however so far so good.

These are an updated version and now have a 10 year lifespan. First Alert makes great detectors.
