Unbranded Carbon monoxide alarm 5 review

Product alert

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

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 it's unreliable when it comes to detecting CO.

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 three 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.
