The alarm seems very well made and is easy to use and install. It's not much bigger than a room thermostat. We have mounted it on the wall near to our gas boiler. It can be tested by one press of the button where it then sounds 2 sets of 4 beeps. There is a green LED light that flashes at intervals to let you know it's working OK. Fortunately it has never alarmed due to boiler fumes but we feel much safer now we have the detector. By the way, we have 2 of them now one near the boiler and one up stairs on the landing.
