Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital DisplayCustomer Review: Exactley what you need in a Carbon Monoxide detector Summary: 5 Stars
Was looking for a quality all in one Carbon Monoxide detector and this is it. It runs on AC, plugs right into the wall, has a 9v battery backup (*BONUS*battery was included) and has a digital display so you know it is working. Price was excellent and I would gladly recommend this to other people.
Customer Review: Excellent carbon monoxide detector Summary: 5 Stars
We bought this particular detector because they are used where my husband works. He works in a warehouse where propane forklifts run all day, all seasons of the year, and Kidde is the brand they use. They work quite well there, so we figured they should work equally as well in our home. It does. I especially like the ability to place it directly in the electrical outlet or to hang it on the wall above the outlet, or place it on a shelf near an outlet. The battery back-up is another plus, as we sometimes lose power during storms.
Customer Review: False Alarms Summary: 1 Stars
This is the third Kidde Nighthawk that we've owned and all have exhibited the same behavior - after a little more than a year they produce a false alarm in the dead of night. How do we know the alarms are false? First, the alarm isn't continuous. The unit sounds long enough to get us out of bed and get our hearts pounding and then stops. Second, the display reads 0 ppm CO. Third, when we check the peak level of CO it is always below the threshold level where CO would be a concern. I have tried replacing the battery even though "LB" is not displayed. The result is the same behavior and frustration a week or two later. Our first two units were the combined CO and explosive gases units which others have noted are problematic. However, we have had the same problem with this unit (CO only). Interestingly, the alarm usually sounds in the summer when we have the AC on, rather than when we are heating the house with natural gas. I'm wondering if others have had this problem.
Customer Review: False Alarms, but great warranty & hassle free Customer Service Summary: 3 Stars
I JUST barely sent an email to this company about the bad battery life and false alarms I was getting with this particular device. SINCE it was still under it's 5 year warranty they are sending me a new device in 7-10 days...hardly any questions asked. So, as far as customer service is concerned I'd give it 5 stars, the device itself, still unsure about. I have yet to really know if this device WORKS properly as I have only been using it a few months.
Customer Review: Great Product Summary: 5 Stars
Great product but I later found out I could have paid less at a local store.
