If you’re looking for a device that needs minimal maintenance, then the FireAngel CO-9X Carbon Monoxide Alarm may well catch your eye.

We’ve tested its detection of killer carbon monoxide in a series of stringent lab tests to see if it pairs convenience with the quick reactions you need to keep you and your family safe in an emergency.
