This carbon monoxide (CO) alarm failed to sound in one of our initial carbon monoxide detection tests. Because of this, we’ve made it a Don’t Buy. It’s sometimes known as the JKD-512COM, and in other listings it’s unbranded. Our tests show that you can’t rely on it to detect carbon monoxide every time, so our advice is to give it a very wide berth. If you have one in your home, replace it as soon as possible with an alarm from a well-known brand, and buy from a high street store or reputable online retailer. Check out our Best Buy carbon monoxide alarms to see our top-scoring models.
