Lifesaver Carbon Monoxide Alarm 5CO review

£17.00 Typical price

Test score %

Reviewed

The Lifesaver Carbon Monoxide Alarm 5CO comes with replaceable batteries that you’ll need to change every two to three years during its seven-year lifetime. In return for this upkeep, you’d expect to be able to rely on the Lifesaver Carbon Monoxide Alarm to live up to its reassuring name. To find out if this trust is justified, we tested it against four different levels of the poisonous gas in our test lab.
