This post isn't so much about this particular product (although it is a good price - Was £25) but more to raise awareness about this silent killer and why EVERYONE with Gas boilers in their home should have a 'working' Carbon Monoxide alarm.
Apparently, according to the below info (follow link below), these alarms are being reduced this month in most stores to around £15.
Although if any of you know of/see a good deal then please post it here so it may encourage people to go out and buy one.
So everyone PLEASE get yourselves one and make sure you keep your gas boilers, chimneys etc. regularly serviced.
