Basic carbon monoxide detector
- Accurate and durable
- Inexpensive
- No display
- Must remember to change batteries
Consumer Reports magazine tests and rates 20 carbon monoxide detectors, including the Kidde KN-COB-B, in its 2008 category roundup. Owners post their reviews at Amazon.com.
The battery-powered Kidde KN-COB-B basic carbon monoxide detector performs well in tests and is cheaper than the top-rated Kidde KN-COPP-B (*est. $40) because it lacks a digital display. Bear in mind, though, that most experts prefer CO detectors with digital readouts, which continually display carbon monoxide gas levels in the home and can alert you to borderline levels that may not yet be dangerous. The Kidde KN-COB-B has a green LED that flashes every 30 seconds to indicate that the unit is working properly, a test/reset button and multiple mounting options.
