VERY ATTRACTIVE, includes batteries as well!
I had a bit of a time getting the back off to insert the batteries, but once I read the directions fully, I saw my mistake, and then I was able to insert and attach them just fine. The box includes VERY specific instructions as to where to hang this AC/DC powered unit. Good information if you have never had one before. It is very LOUD, it will wake everyone up if there is ever a problem!! A wise investment for any home.

Good CO alarm
Good CO alarm. Works well and has a loud alarm. Be sure to have a replacement battery available. When the low battery alarm goes off you will want to change it out ASAP! Uses about 1 battery per year. Unit life is about 5-6 years, then will have to replace with a new unit. On my 2nd one

    Lasts 10 years - Monitors Carbon Monoxide
    Easy to install, just put batteries in the back, plug in and set on a table. Since you can't smell Carbon Monoxide, it's a good idea to have one of these on each floor of your house.

    works great and easy to set up, was extremely happy to see that my house reads 0 carbon dioxide even with an oil furnace and gas oven and gas dryer, love the digital set up.

    Cord or no cord,that is the question
    Ok- cord option seems good but do you really need another long thin tangly cord in your life.

    Good product
    We chose the plug-in option with battery backup. Battery easy to install. Our previous CO detector died so wanted to replace for our own peace of mind.

    Good CO detector - lasts 10 years now
    Bought this to replace the exact same CO detector which lasted 7 years as promised. We use it in hallway to bedrooms for peace of mind. Display clearly states when battery is low or end of life, so that you don't have to do any guesswork (there are 2 smoke detectors too in the hallway, so it can get confusing with low battery beeps)

    Kidde NoghtHawk plug-in CO alarm
    This is the 2nd one of these I've had. Very convenient to be able to plug into an outlet. When backup battery is low & it beeps, it sounds exactly like the smoke detector. When/if you hear the low battery beep every 30 seconds, check the CO detector first since that is a lot easier than getting on a ladder to replace smoke detector battery & find it didn't help. I haven't had a CO problem so it hasn't ever alarmed.

    just what I needed at reasonable price
    This product was recommended by a gas employee doing a home energy inspection. Simple, buy it, put battery backup in & plug into any electrical outlet - done. Best part, shows that even with our 19 yr old furnace, we are carbon monoxide free. completely satisfied, time will tell if units are truly a good value.

    Good quality, low price
    After having a new air conditioner installed in my house, I thought it would be a good idea to check the age of my old carbon monoxide detector. It was over 14 years old! The Kidde NightHawk got good reviews so I ordered it online and picked it up at my local store. It exceeded my expectations. Battery backup, plugs directly into the wall and also has a wire extender to plug it into the wall but mount the unit away from the outlet. Very simple operation and gives good piece of mind.

    Great peace of mind...CO monitor
    This replaces my 7 year old monitor of the same model. I a bought a second one to replace my First Alert. This is an easy 'plug in' with a battery back up...battery furnished. I like this one especially for the digital readout that is continually showing the CO level, normally at zero and it's working .... the blinking dot.
