The digital readout of the Kidde Plug-In Digital Carbon Monoxide Alarm with 9-Volt Backup continuously displays carbon monoxide levels from 30 to 999 parts per million (PPM) and will sound an 85 dB alarm when dangerous levels are reached. The carbon monoxide level sensed is continuously displayed and updated every 15 seconds, and the peak level memory shows the highest level of carbon monoxide present since the last time the unit was reset or unplugged. Protection continues during power outages thanks to a 9-volt battery backup.

I bought this because of its digital readout and max CO level memory. After reading the directions I realized that it has a built-in power adapter ("wall wart" style) with a long cord neatly stowed in back, which allows this unit to be directly plugged into an outlet, or the adapter can be plugged into any outlet while the main unit is resting on a table top (stand included) or is mounted on a wall at a more comfortable reading height than the outlet is located.
Pros: Easy to Use, Nice Design, Easy Installation

Review 5 for Plug-In Carbon Monoxide Alarm with Digital Display and 9-Volt Backup
I bought a Nighthawk plug in in 1996. It's now 2012 and I never realized it need to be replaced. OMG, it just went off at 5:00AM this morning. I found that the side venting furnace had a large hole on the top side of the duct due to rust. CM was leaking into the basement and carried up stairs. My wife had complained about headaches, but we never connected the dots until the alarm went off.
Needless to say I'm buying 3 more today! Thanks, NH

Review 7 for Plug-In Carbon Monoxide Alarm with Digital Display and 9-Volt Backup
I bought two of these and they both lasted almost exactly seven years. I purchased them in Feb of 06 and they both displayed Err messages within a week of each other in Feb of 2013. I called Kidde and they told me that they normally last 7 years and then need replacement. Hard to believe but I need to more. Be aware that I was told that it seven years from production date, the date is on the back of the unit. My alarms were both made in Sept of 03 so they had been on the shelf for three years when I bought them. Make sure they are current year production when you buy yours.
Pros: Easy to Use, Great Sound Quality, Loud, Battery Length
Cons: Burns Out

Third and fourth units we've had in homes. Both previous units lasted 10 years and performed perfectly. Features AC power, 9v battery back-up for power outages, loud alarm, easy to test, easy to read digital display, ability to monitor low CO levels and re-set. Competitive price.
Pros: Lots of Features, Easy to Use, Loud, Easy Installation

Review 10 for Plug-In Carbon Monoxide Alarm with Digital Display and 9-Volt Backup
We've had 3 nighthawks and I am purchasing the fourth one. This last one lasted 8 years. We love this product. It never fails. The alarm went off once. And it was due to the gas burner being left on accidentally by someone in the household (could have been me). We leave one upstairs (kitchen) and one downstairs (basement). I personally have encouraged people to buy it and will continue to do so. I am a kidde safety fanatic. We have 3 combo alarms, 2 nighthawks and 2 home fire extinguishers. Can you guess what I do for a living? I am an ER nurse.

Review 11 for Plug-In Carbon Monoxide Alarm with Digital Display and 9-Volt Backup
I finallly got an error message and the manual said to call the company. They asked me for the manufacturing date, which was 8 years ago (which is probably how long I've had it), and said it is simply time to be replaced. I plan on buying another one just like it.

Review 15 for Plug-In Carbon Monoxide Alarm with Digital Display and 9-Volt Backup
For most of my adult life I have worked with gases and flamable's. I have seen first hand what deadly things we can't see, can do. It just makes sense not to want to be killed by something you don't know is there. CO gas can't be smelled, or seen. This Kidde Unit measures the air for dangerous levels of this culprit. It constantly monitors your homes air for the dangerous killer. You just put the back up battery in and plug it into the wall. I would hate to get the the pearly gates and have to explain how I got there, when this thing is available. It's a small price to pay for your families safety.
Pros: Great Sound Quality, Loud, Lots of Features, Eco-Friendly, Clear Instructions, Nice Design, Easy Installation, digital display to see the co levels
