Kidde Long Life Carbon Monoxide Alarm 10LLCO review

£18.00 Typical price

Test score %

Reviewed

The clue is in the name of the Kidde Long Life Carbon Monoxide Alarm 10LLCO – it should last up to 10 years before you’ll need to replace it. Along the way you won’t even need to replace the batteries, which are safely sealed inside the unit. But does it pair this long life with the ability to detect even small concentrations of carbon monoxide in the air? We put the Kidde carbon monoxide detector through a series of gas detection tests to find out.
