Bests & Worsts Reviews from Amazon

This is a very convenient unit to install and figure out. I like the digital display because you can see the CO levels and can get a sense of any issues by simply glancing at the unit when walking by. I liked that it came with brand name batteries too, when I was looking at my local hardware store some of the units had generic batteries. The reason I bought a Kidde is the built in functionality. I had a smoke alarm of theirs that was acting funny, beeping every 30 seconds, so I pulled it down and right on the back it listed what each beep sequence meant (no having to hunt for a manual, or search online). This unit acts in the same manner, it's even supposed to alert me in 7 years when it is time to replace the unit, how cool is that?
