Simple to use, works well,
Verified Purchase(What's this?)
This review is from: First Alert CO600 Plug In Carbon Monoxide Alarm (Tools & Home Improvement)
I purchased this for my Mom, who has a very low tolerance for any type of electronics that has more than one button. This fits the bill perfectly -- just plug it in, and it works. Other models have more advanced features, such as a digitial display or a batter backup, but if you're looking for simplicity and a low cost, this is a great choice.
