Review: Reliable and Ideal for Boats/Caravans etc - This is the 3rd of these units I've purchased, one for the house and two for boats. They are ideal for the latter as they meet the spec for damper/colder environments. The peak display gives assurance you haven't got anywhere near a dangerous CO level. Highly recommended if you have a solid fuel stove or gas hob/oven. Review: Old one showed an END message after over ten years - Purchased this as a replacement for one which had cone to the end of its life. Amazingly when I checked the installation date my old one had been sitting in my kitchen next to the boiler for 10and a half years. Over ten years of protection for my family for a few pounds has got to be fantastic value. Great quality unit that this time was installed by simply popping over the screw from the replaced unit. A must have for every home. ## Features - Battery powered carbon monoxide detector with 10 year sensor life, backed by a 10 year warranty. - Digital display of CO readings.
