Nice features and easy to install

We needed a battery operated unit and wanted one with a LCD display. This unit is nice as it shows current battery level and if you want to see peak the display is easy to read. Great value and well built

Excellent Service

The CO detectors arrived very promptly and in good condition. The First Alert Store is a much easier source of CO and smoke detectors than I was able to locate on-line.

Carbon Monoxide Alarm

Our old alarm had reached its expiration. We ordered a new alarm at the First Alert online store. We received the replacement alarm in a few days, and installed it with no problems what so ever. Like the backlit battery life display.

Love this Unit

The display is great and I think the AA batteries fit more secure than a 9 volt model. This is my third one I purchased!

Great product

Love the display to show battery level, Co level - current and peak. Removes all guess work. Battery compartment has easy access in the front. I like this model over my other First Alert unit models.

Consumer Reports rates this CO alarm as the best stand alone battery operated one. Yes, there are more highly rated CO alarms, but they must be connected to a house electrical circuit. Also, it is less expensive than many of the others. Since the experts recommend that each bedroom and hallway have a CO alarm, most homes need at least 4 or more of these. So the savings on this alarm are actually increased by at lest 4 fold.

Better CO detector

I bought this to replace an older First Alert CO detector that had reached end of life. It fit on the same mounting screws as the old one and the LED screen is a nice upgrade. It lets you know when the battery is low before it starts chirping at 1am.

Excellent Replacement for CO400

This was a perfect replacement for a CO400 that reached its end of life. The mounting holes lined up perfectly, and the unit was easy to start and test. I like the display.

Works & Looks good

The detector was shipped on time and it worked great out of the box. I like the fact that it uses less expensive AA batteries which can be easily accessed and replaced in front of the unit. I hope it lasts me as long as the older model I replaced.

Long lasting.

Purchased 4 of these with mfgr date in early 2011. Installed upon receipt. First of them just gave End Of Life signal, almost exactly 9 years later. No problem with any of them over that time. Easy to use and install, that's why I'm replacing old ones with the same thing.
