Fire/carbon monoxide alarms
My alarms needed to be replaced and I could not find them locally. On line I ordered and they work perfectly.

Time to replace as they have a limited lifespan
My home has 11 of these combo smoke/carbon monoxide detectors hard wired throughout our home. They were installed when the home was built (2014) and reaching end of life. These a exact replacements and overall the quality is good. These newer units have 10 yr life so hope to get longer life but we'll see.

Happy, great price
Not much to say, but I was pleasantly surprised these came with batteries included. Quick replacement of my old ones that were 7.5 years old and started chirping they were done.

Very easy installation
Replaced three First Alert smoke detector model no. 9120B. These SC9120B use the exact same wiring harness. Lowe's sells the single detector for $49.98 each. Lowe's did not offer a 3-pack.

Quality product at a reasonable price.
Liked the three pack, had two units go out in same week, and the three pack price worked well, saving a few dollars. Every dollar saved helps with what the joe-bama/commie MALADY administration is doing to our country and we the people.
