I bought 2 of these for upper level and the ground floor. I plugged in yesterday, and today is day 2 . This item works great monitoring CO level , humidity , and smoke detection. I surely recommend this for every house hold.

Just received this detector and set it up—super easy plug-and-play. I like that it combines CO and smoke detection with temperature and humidity readings all in one screen. The display is clear

This is an excellent product, large screen, easy to read, the plug and magnet options are super useful if you want to use the same device in different places. The set up is a breeze.

So far, so good. The device is easy to use, and provides info on the CO2 leveles, smoke, temperature band humidity. Very compact.

Great CO2 and smoke detector all in one. It's a plug in and go.

This is a very stylish, modern home devise- handy, compact, competitively priced, CO/Smoke, Detector with Humidity and temperature (F and C degree) reader. Easy to read screen/data features, dual powered (plug or battery alone) so it can be used any where. Additional information since my review/and purchase (just weeks ago) I would add that I have no experience concerning how long the unit will actually last.

This is smoke and carbon monoxide detector that also give you humidity and temperature in the house. Overall is a great product with a really easy to read digital interface. You can plug it in at home or take it with you on the road. It feels like a solid addition for peace of mind at home.

Cool design, and really like the Temp and Humidity added features.

Nice and compact compared to my old one, which stopped working.

Excellent product.. has aesthetic appeal as well besides meeting functional requirements
