I like the smoke detector. The ten year batteries don't last more than a single year. Second, who tests a smoke alarm and resets it once a month?? That's the directions. Third, if you have any dust (country living) or the little night bugs like gnats and mosquitoes....they are attracted to the power light and set it off as they get inside the unit. You'll need to use compressed air to blow them out. The alarm I bought that caused this rating is a replacement for the one I kept blowing out, and yet it continues to chirp....after a week or so, and in the middle of the night....

I love the battery door right on the front of the unit. Easy to install new battery. This unit comes with adapters for replacing other brands of hardwired detectors. I had a First Alert unit that needed to be replaced, but it was so old that the adapters would not work. I had to wire in the new plug which was a bit disappointing since I paid extra for the unit with the adapters. The wall plate was not large enough to cover the old detectors footprint. This left a small area that needed some touch up paint to cover.

Mostly giving this a good rating for the price, which with these being on sale made it super worth the cost. The instructions aren’t super clear on how to replace them and they aren’t compatible with the ceiling docks from the previous model, so you have to remove the old docks and install the ones they provide in the packaging. Overall very easy and if you get confused just watch YouTube.

Bought to replace my original hardwired battery-back up alarms, these were the same in terms of the power connector style (and also came with an adapter), but wouldn't work with the original ceiling brackets, which was no big deal since they include new brackets, which were very easy to switch out. Once the new brackets were on, I did have to push on each unit pretty hard to get them to catch on the bracket, but it was doable. All in all, probably took about an 60-75 minutes to replace 5 of them (and that includes having to cut open some of the plastic packaging, which as we all know is ridiculously hard, leading one to wonder if the scissors are really that dull, if one's already beginning to lose strength with age, or why there are still so many non-recyclable, non-compostible materials being used when there are better alternatives)? Definitely recommend these smoke alarms. Hope they last at least the 9 years that the original alarms did before all deciding to start screaming at once for no reason until we disconnected them. I have a good neighbor, though, who immediately texted to ask if everything was okay. There are still good neighbors in the world who live in peace and look out for each other, regardless of political, ethnic and other differences. Oh, and the smoke alarms really are excellent for new or replacement installations. I would absolutely buy them again. I also appreciate that the little green light is less bright than on the original smoke alarms, because I had to stick blue tape on the original alarm light to prevent it from keeping me awake, but the glow on the new ones is more gentle, so doesn't keep me up). Great design and function!
