Rated 5.0 out of 5.0 by Gina Easy to install, reasonable price.
All you have to do is insert two fresh AA batteries into the battery compartment in the back of the device and then plug it into a standard wall electrical outlet. The green light indicates they're working. I had to buy these for an appraisal inspection in connection with a refinance on my house (needed one for each floor), and they did the trick. They're easy to test and squeal loudly when tested, but the sound is very brief. My house is a newer one, so I doubt I will ever have a CO problem. I assume these would work if there were one, but I hope I never have to find out. If I had not been required to have these for the re-finance, I would not have bought them. But for about $100 for the two, it was well worth it in order to qualify for a great rate with no points. Cheap, easy to install, test without difficulty, and satisfied the appraiser. I'm happy with the purchase.

I plugged it in the outlet and hit the test button and it sounded. So I suppose the unit will work when and if it is needed!

I like the plug in feature. Hard to really test out since I don't have CO in the house. But seems like it's working fine.

Rated 4.0 out of 5.0 by Anthony Good alarm
This alarm is powered by an AC outlet but also has a battery backup in case you lose power. The batteries come already installed. All you need to do to use the battery backup is to remove a plastic tab that is coming from the battery compartment. The light on the front indicates if something is wrong with the unit or air quality. Green is good, red is bad. The instructions state that the unit does self checks to ensure everything is working correctly.
There is a test button on the front. When pressed, the alarm sound is nice & loud & will certainly alert most people that something is wrong.
I would definitely take the 5 minutes to read the instructions when you install this. There is a lot of good info in there, and some minor details that are good to know about this device.
Lastly, this alarm is good for 10 years once powered up. After 10 years, annoying alarms will force you to throw it away.

I thought I was going to have to wrestle this unit out of the plastic, but it has an easy open design with perforations in the plastic (see photo). Item looks nice, functions well and is reasonably priced. Only wish Kiddie, "the worlds largest manufacturer of fire safety products," had a recycling program and/or cradle to grave business model. They state in their core values that they "are environmentally responsible and drive to sustainability." By doing what...?
