Offering a market-leading 10-year lifetime, the FireAngel W2-CO-10XQ promises a full decade of service before you need to replace it. Does it pair this long life with a first-class ability to detect poisonous gas? To find out we put this carbon monoxide alarm through a full range of safety tests, assessing everything from the clarity of its alarm sound to how sensitive it is to four different levels of carbon monoxide.
Is it worth your money?
Or is it a waste of cash?
