Review: Awesome - It’s hardwired and plugged into my existing system. Really easy to install and I’m a senior citizen.
Review: Nice Alarm, Easy to Install - I bought this alarm to replace an older failing alarm that would randomly go off (usually in the middle of the night). I like that this has a digital readout so I can tell if it is a false alarm or if I really do need to evacuate the house. It installed very easily, having a 3-wire hookup for power and connection to other home alarms. It took me all of 15 minutes to screw the back of the alarm to the gang box, connect the wires, twist on the cover, and perform a quick test. I haven't had a false alarm since (crossing my fingers). The only suggestion I have is to provide a place on the front plate where you can place a sticker or write the expiration date of the alarm. This alarm will stop functioning after 7 years and it is easy to forget even as you change the battery. I ended up taking a sharpie and writing the expiration info on the face, so when the alarm goes off in 7 years, I or the new owners of the house will know why.

### ⭐⭐⭐⭐⭐ Really like this CO detector
*by T***V on November 27, 2017*

Really like this CO detector, it just saved us a few days ago. Every 15 seconds or so (I didn't time it, don't quote me) it take a reading and will actually show you on the display what the CO concentration is. Hopefully it's zero. I didn't know that closing too many vents can cause your furnace not to be able to properly clear exhaust. So I went around shutting vents in rooms we don't use very often. A while later this starts beeping. I thought it was the battery, but then I looked and the readout was 90, it was detecting unsafe levels of CO in the house. Shut the furnace off, opened up the house to air it out, ran the fan to move fresh air around. Looked it up and lack of proper airflow can cause that to happen. So I opened vents back up and it hasn't happened since. None of the older detectors in the house alerted because it wasn't crazy high levels yet, but this one warned me way ahead of time. Well worth it when your little girl is napping.
