Review: Peace of Mind That Doesn’t Scream “I’m Ugly” on the Ceiling - This First Alert combo smoke and carbon monoxide alarm does exactly what it’s supposed to do — protect your home — and does it without being bulky or obnoxious. The slim design is a big win. It sits flush and clean on the ceiling or wall and doesn’t look like a giant plastic UFO hovering over the room. Setup was quick and easy, the battery operation means no wiring headaches, and it feels solid and well-built. Knowing it’s watching for both smoke and carbon monoxide is huge peace of mind, especially at night or when you’re not home. Basically, it’s one of those products you hope never has to prove how well it works — but you’re really glad it’s there just in case. Reliable, simple, and smartly designed. Exactly what a safety device should be.
Review: Easy to install and worth every penny. - These combination detectors are really good and worth every penny. I had one prior to this one same brand and unit but disposable with a built-in battery. I like this one because I can replace the batteries, it uses 2 AAA batteries because it's so thin and will let you know when the batteries are low.
