Expert review

This carbon monoxide (CO) alarm is dangerous and failed to detect CO in two of our carbon monoxide detection tests.  Following these gas detection failures, we've made it a Don't Buy and our advice to you is to steer well clear of it. If you have one in your home, you should replace it with a well-known brand from a high street store or reputable online retailer.
