First Impressions CO 605

The alarm came well packaged and was easily installed. I did peruse the instructions just in case. I feel better having the alarm, a friend of mine had a real scare some years back and luckily was able to get up and out of the house. His quote saying,My family almost died. said a lot about his week end back then.

plug in CM alarm

I assume the product will perform as expected. It was very difficult to open battery compartment to install battery

Exactly what we ordered

Ordered 15 of these detectors and they go here super fast. A couple days early and seem to be working great!

Long-lasting protection

I installed these First Alert CO Alarms in both my primary residence and in a condo where I live part-time. They've been dependable monitors and have lasted seven years. Recently they reached the end of their life spans, and I'm replacing them with the same alarms.

Great for peace of mind!

These carbon monoxide alarms are perfect! Electric plug-ins plus battery backup - and small enough to be inconspicuous!

SAFETY FIRST WITH FIRST ALERT

This is a great carbon monoxide detector. We have 2 that we are replacing after 10 years of use on a single battery. Plug in with 9V battery backup. Never can go wrong with First Alert products!
