No Battery Backup...sweet!,
Verified Purchase(What's this?)
This review is from: First Alert CO600 Plug In Carbon Monoxide Alarm (Tools & Home Improvement)
I am part of the contingent who does not need battery backup because none of the conditions exist for me to need it. So, dead battery annoying beep warnings are a thing of the past. And the price is right too. Regarding those who complain about no battery backup and deduct stars...the product does not claim to have a battery backup...it is right there in the description and so at best all that should be noted is that it does not have one. Taking away stars because the alarm does not also brew your coffee in the morning is just plain silly.
