This a Don’t Buy carbon monoxide alarm. In our tests so far, it’s been dangerously unresponsive in the presence of CO, and should be avoided. It doubles as a smoke alarm, and it was just as bad when we tested its smoke detection abilities. We bought it from a seller on eBay, but you’ll also find it listed on other similar online marketplaces. If you have one in your home, replace it with a well-known brand from the high street or a reputable online site. See our Best Buy carbon monoxide alarms to find a model that won’t let you down.
