Best and Easiest Smoke & Carbon Monoxide Detectors to Install!
These are by far the easiest smoke and carbon monoxide detectors I’ve ever installed. The 10-year battery is a big plus—no more worrying about changing batteries every year! All you have to do is screw the holder to the wall, place the unit on, and give it a quick turn—that’s it. Simple, fast, and reliable. I’ve tried other brands, but these are definitely the best and easiest to install.

Easy to Install – good quality.
Easy to install- seems like good quality – is not chirping at me. Basically so far doing everything you want in a smoke alarm

Complete garbage
If I could give these no stars I would. I purchased 2 of these in Feb to replace some old wired smoke detectors. Install was easy. The trouble came in Sept when one of them started to malfunction and give an alarm all the time when there was no smoke or heavy fumes. Nothing. Also it was not a CO alarm but a smoke. At all hours of the day and night. I finally got so sick of it that I pulled it off the ceiling and wrapped it in a blanket as my poor dog was shaking violently every time it went off. Put it back up a week later. Same problem. So I tossed it.Now here we are in Nov and the other one I bough is doing the same thing. Going off for no reason. Even wrapped in a blanket it was still going off. So I put it out on the porch. With fresh air and everything. And it continued to go off sitting outside intermittently for 2 more days before it too went in the trash. We are of course outside the return window. So I spent $80 to not have any smoke detectors in the house and will have to shell out more money again to buy another brand. These werent old. Both had been up less then 9 months when they malfunctioned.Dont waste your money on these unless you like your pets being traumatized at 2am when the thing randomly goes off for no reason and wont stop.

one year later
after one year, almost to the day, it started chirping 3 times which indicates a bad unit. So, blew it out with my air compressor and the chirping seems to have stopped. waiting to see what happens.

I think I might replace all of my smoke detectors with this type.
Low profile. Super easy to install.
