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.

Impressive features
I liked the LCD display which gives accurate readings of faults rather than just a beep!

We haavn't been gassed yet!
Great detectors. We bought one for each floor of our house. It's discreet, with a flash once a minute to tell you that it's still operating, while lot attracting too much attention. It's easily fitted and has a good slide on bracket that fits to the wall so the detector can be removed for examination and easily slid back into position.

CO alarm with the benefit of an LCD display
Replaced the previous model from Kidde with this one. The other one served us well for nearly ten years. I like the feature that it has an LCD readout showing the level of CO, rather than just sounding an alarm if the level is too high.
