These are easy to set up. Love the fact they are not so sensitive they go off with normal cooking like one we had. Yet they are loud enough to alert you to any problems and will tell you when they need to be discarded and a new one put up.

I was delighted this updated version fit the original mount. It was a 30-second job to put in the batteries & twist it into place. Good job, First Alert!

Easy to fit. Previous model lasted ages between battery changes. Impossible to ignore noise.

Meant to order the version that is hardwired with battery backup, blame it on me looking at too many similar items. At any rate this model is alright! I'll simply replace the batteries twice a year.Pros: Alarm for both smoke & carbon monoxide. Super easy to install & test. It's very, very loud--as needed for an alarm. Can be programmed to say a specific location in the voice alarms, great if you use more than one of these in a bigger house. AA batteries more likely to be lurking in your junk drawer than a 9V! Easy to replace batteries in slide-out drawer. Being battery-only makes it easy to install in any location without extra electrical drops needed.Cons: No hardwired power supply. Power lights are tiny & barely noticeable, plus they flash instead of steady light. Voice alarm isn't as clear as some higher priced alarms are, sounds a little tinny & muffled. Button for testing & quick shutoff is a little small & has a ridge partway around it so won't be as easy to whack it with a broom handle if it goes off unnecessarily. (Haven't burnt any toast yet, not sure how sensitive this model is)

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).
