Unbranded Carbon monoxide alarm 6 review

Product alert

Don't Buy this carbon monoxide (CO) alarm – it failed to sound in all 38 of our carbon monoxide detection tests

This alarm simply can't detect carbon monoxide (CO) and should be avoided. In our tests it failed to detect the gas every single time and that's why we have made it a Don't Buy.

Expert review

This unbelievably dangerous carbon monoxide (CO) alarm failed to detect the deadly gas in every single one of our 38 tests. That’s why we’re making it a Don’t Buy. We bought it from eBay, but it’s also available from other online marketplaces. If you have an alarm that looks like this in your home, your best course of action is to replace it with an alarm from a well-known brand that you buy from a high street shop or reputable online retailer.
