Reviewed

Bought from an online marketplace, this is yet another cheap and unbranded carbon monoxide (CO) alarm that you simply can’t rely on to detect CO. We’ve made it a Don’t Buy, as our test results show that after failing to detect CO eight times, it’s more likely to endanger lives than to save them. If you have one in your home, replace it with an alarm from a well-known brand that’s available on the high street or from reputable online retailer. Check out our Best Buy carbon monoxide alarms for our top recommendations.
