  • Perfect replacement
Style: Standalone Model Size: 5-Pack
The size is perfect to cover the existing hole for my old, wired smoke detector. Easy to install, no need to re-wire. Just need to drill a hole to the mounting plate to line it up with the existing screw holes. Hope the battery last as advertised. Good product, quality made.

  • Good quality, but mounting plate may require alteration
Style: Standalone Model Size: 5-Pack
Nice 10 year smoke detector, only issue Ihad was that the mounting plate did not have the openings for a standard electrical ourlet box. See pictures. I used the original old plates to mark and then drilled holes to finish the job. Not hard to do but you’ll need to drill holes if you want to use the electrical box for the detector. ... show more

  • Great product.
Style: Standalone Model Size: 1-Pack
So glad Amazon offered this product. 10-year product life and I don't need to worry about an alarm going off in the middle of the night because of battery failure. My son installed 8 of these alarms in no time at all.

  • Good value
Style: Standalone Model Size: 1-Pack
These are my favorite smoke detectors. They are light weight and east to twist on and off the base. There is a small switch that is depressed and held down when the detector is twisted onto the base. These detectors must be installed using the included hardware. I tried with different screws, but the head sticks up too much for the detector to twist into place. Because of this it would be nice if a couple extra screws were included just in case one of the tiny hard to hold ones becomes lost. ... show more

  • 10 year battery, enough said!
Style: Standalone Model Size: 1-Pack
I've had this for a few months, and test it monthly. So far it has done exactly as it should. Nice not to have to tear it apart if it starts beeping, just twist off base and it stops! I absolutely love knowing my grand babies are safe in their room and The house will be notified of any issues. And not worrying about changing (or forgetting to) batteries every 6 months is a real benefit, since all my clicks do daylight savings on their own... which is how my volunteer fire depot Dad always taught me to change the batteries during those events. ... show more
