I have 2 of these detectors at home and they are the business, easily the best on the market from a well known brand in fire safety.
The digital display is no gimmick but actually a very useful indicator of CO levels.
Battery powered carbon monoxide alarm with digital display to constantly show CO levels detected. Features include peak-level memory to show CO levels detected since unit last checked.
