Not so fast, has some issues
Plugs In Wall
Battery Door Bad Design
Made By First Alert
Best Uses
I bought this based on CR recomendations and it is fine and I use it but, I would not recomend you buy this because the battery door is poorly designed and does not stay closed.<br />Also, and this is an issue with Kidde and other brands and smoke alarms too, the alarm sound, when it goes off, is LOUD to the point of hearing damage. OK, yes, we need that during a real alarm. But when you unplug it from the wall, it alarms off the battery at full horn! WHY don't the engineers make it so the full alarm ONLY happens when actual detection happens?!<br />Over the past 20 years, 75% of the First Alert smoke alarms I have bought have failed in the first 1-5 years. But I also bought Kiddes and, never had any problems with them so. I am now only buying Kiddes.

Purchased based on CR recommendation. Didn't last a year. Went into remove to fresh air state for no reason and never came back. Will never buy another First Alert product. Second time buying based on CR recommendation, second failure.

Display difficult to read
Best Uses
Living Room
We purchased this alarm at a [@] in 2010, so we've owned it over a year. Our 50-something eyes have some difficulty in reading the grey display, but there is a red light to show that the product is working and, if an alarm were to sound then the red light would flash. Very loud beeps, including once every minute when the battery is dead. (FYI: My husband slept through these beeps, but I did not. If you are a heavy sleeper, I would suggest putting it in your bedroom; we had ours in the Living Room, but have since moved it upstairs to where we sleep.)
How long have you owned it:

Bottom Line
Yes, I would recommend this to a friend.
