Tools and Hardware Reviews of the First Alert CO400 Battery Powered Carbon Monoxide Alarm

Tool Review: goes off every 3 months and needs reset
Summary: 2 Stars

These kind of things are hard to review, since chances are you won't ever have it go off.

Mine goes off nearly exactly every 3 months, and I need to remove and replace the battery. I think it's something with the sensor gradually 'filling up' with the low level of monoxide.
