Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display
Customer Review: It's OK but didn't work at first
Summary: 4 Stars
When first plugging the unit in inside the house I had a problem with resetting it and getting the level to read zero (with several attempts). I thought I might have a carbon monoxide in the house at first but took the unit outside and plugged it in in the garage and it reset to zero with no problem. After moving it back inside the house I plugged it in and now it works just fine. I still don't know why it [messed] up at first or mabey if I didn't do something right, but it was very frustrating. The good news is that it appears to work great now.Customer Review: DO NOT BUY!!!!!!
Summary: 1 Stars
Bought one of these at one of those big box home stores. After about two months of use in a bedroom the thing started going off. Public service found nothing wrong and the other two older detectors were not detecting anything. Took it back and exchanged it and the new one started going off for no reason too. Public service again checked and found nothing, told me they'd had several other similar calls lately. These things are either defective by design or break down easily so if you want to sleep at night DO NOT BUY THIS MODEL!!!!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: BEWARE OF SHELF LIFE OF PRODUCT
Summary: 3 Stars
I started receiving an err code on the unit earlier this afternoon. I call KIDDE...the company in the owners manual that is given to call when you receive the err code. The first question asked is what the date is on the back of the unit. Mine is stamped July 2003. The lady informed me that the sensors are only good for 6-7 years.....so my unit is longer "good". Looks like I will be replacing my unit because of this.... just wish I would have known there is only 6-7 year life span on the Nighthawk carbon monoxide detector.Customer Review: A necessary tool
Summary: 4 Stars
A home CO monitor is a safety necessity in every home with combustion sources, whether it be a furnace, water heater, fireplace, gas range, gas clothes dryer, even an attached garage. The Kidde Nighthawk makes it easy- put in a 9V backup battery and plug into the wall. My last Kidde died an early death (4 years) and kept complaing that the "battery was low", even after I put in new ones. Those loud chirps at 2 AM were really annoying. If the new one goes 5 years without doing that, I'll be OK with it.
