I m hoping never to have to put this to the test! I am assuming it will work. It was easy to install and seems to be working. Appears to be well made and sturdy and it wasnt expensive.

A must have
Good bit of kit to offer that piece of mind. Our boiler is in a cupboard in my daughters room so having a good carbon monoxide alarm is essential to me. Simple to install with detailed but clear instructions. You have the option to mount (fixings supplied) it or simply free stand in a convenient spot. Very easy to test that sound on the alarm is working as it should, much like a smoke alarm you simply press and hold the button. There are lights on front which flash to tell you it is working or if there is a fault. It runs on two AA batteries (supplied). An important device to have which I highly recommend.

Great piece of kit
Excellent piece of kit, at a good price. Has more than one signal, the main one of course being the alarm, which results in a flashing red light. When all is well, it simply flashes a green light every 30 seconds. It also has a "memory of CO" function, whereby the red light flashes every 60 seconds if, in the last 24 hours it detected a high level, but apparently not high enough to go full alarm. It runs on two AA batteries, two Duracell versions of which are supplied. Is also nicely designed in attractive beige with rounded corners - where today everything has to be dirge black or grey with sharp edges, so it seems. Supplied with fixing screws and plugs if you want it fixed to a wall.

Good product with 7 year warranty
The alarm arrived today and was easily fitted. Very clear instructions are enlosed about testing and alarm conditions. My reason for dropping one star was because the instructions say on the front that it has a 7 year warranty and yet the product description says 10 year sensor life. Why the difference?
