    • Easy installation.
Style: Standalone Model Size: 1-Pack
Nice quality, good price. Easy installation. Tests out fine. 10-year battery is a big plus. I recommend this smoke detector.

    • Works Fine...
Style: Standalone Model Size: 1-Pack
This alarm has been installed now just for about a half year. It does what it's supposed to and it's no surprise that in this short time the battery continues to work as it should. It was quite easy to install but I'd imagine this would be true of most any smoke detector as the installation mounts all seem the same. But I wouldn't hesitate buying again as long as the price is competitive. ... show more

    • Alarm could be louder
Style: Standalone Model Size: 1-Pack
I ordered this for the 10 year battery. Easy installation in garage. But doubt I would hear it in the bedroom in the middle of the night. Would get another for my ham shack.

    • No battery replacement
Style: Standalone Model Size: 1-Pack
New to me. I didn't know smoke alarms came with lifetime batteries. But these do. Throw them away in ten years (which you're supposed to do with any smoke alarms) and never put a battery in them.

    • Finally, no more beeping!
Style: Standalone Model Size: 3-Pack
Replaced 3 alarms at my dad’s house as I was tired of hearing the constant chirp of at least one of the old ones from dying batteries. Dad couldn’t hear that frequency, so he was not bothered. These installed easy. Test is loud, so I think dad will hear it if house ever catches fire. So nice not to hear chirping and hopefully not for 10 years. ... show more
