It was exactly what I was looking for.

Great product, best price online, period!

I like that one unit can do 2 functions: detect fire and also detect CO2.

It was easyto install using the enclosed instructions. The item worked perfectly. l

Easy installation and use

Fabulou...soeasy to install

Good quality and 2 devices inside.

I put it on the wall and it works great

Good brand like that is both smoke and carbon monoxide alarm. very pricey

Everything everyone else says is absolutely true. What a nightmare this product is.
