@dazinism @SustainableSailing @Dave42W @hembrow @erictopol They certainly are. I paid less than £30 for our #CarbonMonoxideAlarm. It has a ten-year battery. You just place the unit on a shelf where the manufacturer tells you and try to remember to test it once a fortnight. It couldn't be easier.

And smoke alarms? Everyone needs those, #LogBurner or no.
