Excellent, easy to use, keep your home safe.
Safety of my children and family is extremely important. This carbon monoxide detector is the best for the money. Simple to use. Works quite well compared to others I have had that are hard to understand. When the electricity goes out, it will reassess when it comes back on. Highly recommend this for your needs.

Seems to work well
The detectors have never alerted but I have peace of mind knowing I have them. I liked them so well I purchased some for our adult children to put in their homes. Easy to use. Just plug one in on each level of your home.

More than just a CO detector. Provides useful Information
This is a handsome CO detector. My city requires a CO detector on every floor when gas heating is installed. This one not only serves that function but also gives me a useful readout of room temperature and relative humidity. However, it is brightly lit and could be intrusive in some environments.
