Rated 5.0 out of 5.0 by AndyS Think it's good......
Got this product because my new house has a ventless gas fireplace. Seems to work fine. It's always been at zero on the gauge the whole time and no one has died. So, I guess all is well.

Rated 4.0 out of 5.0 by dkingma1986 Easy to use and install
Product very user friendly. Very easy to install; basically put the backup battery in and plug it in. Excellent design to rotate the plug to fit the wall outlet.

Rated 5.0 out of 5.0 by astrojohn Replaced expired identical unit
Decent unit, more expensive at HD than Amazon but there are stories about outdated units being sold on Amazon. Since they die after 10 years (my original was only good for 7), it was worth a few bucks more getting it from HD.

Rated 5.0 out of 5.0 by Jaybird Saved my butt
I bought a Nighthawk plug in in 1996. It's now 2012 and I never realized it need to be replaced. OMG, it just went off at 5:00AM this morning. I found that the side venting furnace had a large hole on the top side of the duct due to rust. CM was leaking into the basement and carried up stairs. My wife had complained about headaches, but we never connected the dots until the alarm went off.
Needless to say I'm buying 3 more today! Thanks, NH

No home should be without a CO alarm or smoke detectors. This CO alarm is efficient and reasonable in price. The battery backup is a plus. We've never had an issue with our previous unit and recently replaced a ten year old unit with a new one, as is recommended.

Rated 5.0 out of 5.0 by Tom34 very versatile
I bought this because of its digital readout and max CO level memory. After reading the directions I realized that it has a built-in power adapter ("wall wart" style) with a long cord neatly stowed in back, which allows this unit to be directly plugged into an outlet, or the adapter can be plugged into any outlet while the main unit is resting on a table top (stand included) or is mounted on a wall at a more comfortable reading height than the outlet is located.

Was easy to set up, and I like the fact you can set it on a table or dresser because cord is plenty of long enough to reach location where sitting.

I bought this product to replace my old carbon monoxide sensor which had warn out. It was easy to assemble and install. I like the display which tells how much carbon monoxide is present in the room.
