Reviewed

This carbon monoxide (CO) alarm is dangerous, and has so far failed to detect CO in five times in our tests. We haven’t completed our full set of carbon monoxide detection tests yet, but following this alarm’s repeated failures to detect the deadly gas, we’ve seen enough to make it a Don’t Buy. 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. Check out our Best Buy carbon monoxide alarms to see which models we recommend.
