This unsafe carbon monoxide (CO) alarm has failed to detect the deadly gas in nine of our initial tests, so we’re making it a Don’t Buy. We bought it from eBay, but it’s available from other online marketplaces too. In common with other cheap and unbranded alarms bought from this kind of site, you simply can’t rely on it to detect carbon monoxide when you need it to. If you have an alarm that looks like this in your home, replace it with a well-known brand from a high street store or reputable online retailer. For our top recommendations, see our Best Buy carbon monoxide alarms.
