  • Great Product
Style: Standalone Model Size: 3-Pack
I like that there are three smoke detectors in one package. They were easy to install and come with a 10 year battery.

  • Finally a smoke detector that actually works properly
Style: Standalone Model Size: 1-Pack
Nothing to assemble, battery already installed, just tighten the back and attach it to the wall. Easy to test and lightweight.

  • Great product for price.
Style: Standalone Model Size: 3-Pack
Easy to install. Good quality for the price.

  • It’s very good except no replaceable battery
Style: Standalone Model Size: 1-Pack
I like this sensor works very well and it’s overall nice looking but the only reason I’m giving it 4 stars is cause once the battery dies that’s it you have to replace the whole thing. It is not super expensive but would have been nice to have that option

  • Ten year Smoke Detector.
Style: Standalone Model Size: 1-Pack
I just installed it in my hallway. The test button worked indicating it’s in working mood. So it should last ten years as indicated on instructions. Easy to install.

  • Love this little thing
Style: Standalone Model Size: 1-Pack
My fire alarm dies and I needed a replacement. I was super skeptical about this at first because of the price and even more skeptical when it came and was so small! I kid you not, it's 2/3 the size of my other alarm! That being said, I like it better. It isn't an eye sore, the design is sleek and unnoticeable, it is just as sharp and loud as any other when tested, and is less blinding with its operation light. I like the durability of the base attachment as well. Good quality for the price. ... show more

  • Good Price & 10 Year Battery!
Style: Standalone Model Size: 1-Pack
Honestly I hope to never know if they work great, because that would mean smoke and/or fire. But I didn't want to have to hard-wire them and definitely didn't want to deal with regular batteries. These have a 10 year battery, which is great. My handyman did test them after installing and they are loud enough to wake me for sure. ... show more
