Review: Great look, good price, easy Install. - I picked this up and am gonna have to buy more. Out of the packeage this comes with the batteries needed to work, durecell, and screws. Its an easy two screw install: two screws mount the back plate to the wall, and the monitor slides down on the plate to mount. Aesthetically: it looks like a thermostat, about the same size too. I put this in the middle of the wall towards the end in the middle of the room, and I dont even notice it. I have to tell you, compared to the rest, this looks the best. I bought a different brand and it looks like a huge box... Unlike this! There are about several different alarms to tell you whats going on with the unit. Several different language instructions are included. Review: Reassuring! - Inexpensive without all the bells an whistles of the more expensive ones. I use it at my cabin where I heat with a wood stove. The cabin is small, and non insulated (Northerrn Michigan), and used mainly for hunting in the fall. It operates on batteries---which is fine and dandy since we have no electricity in the middle of the swamp. Over the last 3 years, this has saved our butt on 2 occasions, by going off at night and waking us from our sleep. Both nights were below 20 degrees, so we had the wood stove really kicking out the heat(and rapidly using up the oxygen in the cabin). We exited the cabin, let it air out good, and then reoccupied it. Glad these are dependable. I also make sure to put fresh batteries in every fall. We leave a window cracked about an inch now since these 2 incidents, and haven't had a problem since. ## Features - Battery operated (three AAs included) to provide protection during power outages - Test-reset button tests the unit for proper operation and resets the carbon monoxide alarm - Forty percent longer life than other CO alarms - Seven-year end-of-life warning alerts user to replace CO alarm - Meets the requirements of Underwriters Laboratories (UL) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001P3UO3Y | | Alarm | Carbon Monoxide Alarm | | Best Sellers Rank | #69,894 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #118 in Carbon Monoxide Detectors | | Brand | Kidde | | Built-In Media | Carbon Monoxide Alarm | | Color | Multi | | Customer Reviews | 4.4 out of 5 stars 320 Reviews | | Enclosure Material | Plastic | | Global Trade Identification Number | 00047871072682, 00094718140813 | | Item Dimensions D x W x H | 1"D x 1"W x 1"H | | Item Type Name | B/O CO Alarm | | Item Weight | 8.48 ounces | | Manufacturer | Kidde | | Manufacturer Warranty Description | Seven Year Limited Warranty | | Model Number | 21007268 | | Power Source | Battery Powered | | Product Dimensions | 1"D x 1"W x 1"H | | Product Style | Kidde Nighthawk Battery Operated Carbon Monoxide Alarm | | Sensor Type | Electrochemical | | Style | Kidde Nighthawk Battery Operated Carbon Monoxide Alarm | | UPC | 047871072682 094718140813 | | Unit Count | 1.0 Count | ## Product Details - **Alarm:** Carbon Monoxide Alarm - **Brand:** Kidde - **Color:** Multi - **Global Trade Identification Number:** 00047871072682, 00094718140813 - **Item Weight:** 8.48 ounces - **Material:** Plastic - **Power Source:** Battery Powered - **Product Dimensions:** 1"D x 1"W x 1"H - **Sensor Type:** Electrochemical - **Style:** Kidde Nighthawk Battery Operated Carbon Monoxide Alarm ## Images ![Kidde KN-COB-B-LP Nighthawk Carbon Monoxide Alarm, Battery Operated - 21007268 - Image 1](https://m.media-amazon.com/images/I/61D3V96zbRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great look, good price, easy Install. *by J***. on December 3, 2011* I picked this up and am gonna have to buy more.
