This dangerous carbon monoxide (CO) alarm cannot be relied upon to detect CO and then sound the alarm when you need it to. That's why we’re making it a Don’t Buy. It failed to detect CO in 17 of our detection tests and can't be trusted to alert you if there’s a build-up of the deadly gas in your home. If you have this alarm, you should replace it as soon as possible with a model from a well-known brand.
