Rated 4.0 out of 5.0 by Seems to work fine I haven't actually tried the smoke alarm yet - I bought this package for the carbon monoxide alarm and the package price was better then the CO alarm by itself. I specifically wanted a display showing the CO reading, and this has it. I haven't found any CO to actually see it read anything but 0. But the backup battery kept it going just fine when my power went out. It's a bright red LED with a dot that blinks. I suppose it could be annoying in a dark bedroom, but I find it nice to be able to see it from quite a distance. I'm using mine in the stand on a table configuration, and that works fine. Getting the plug out of the back and setting it up was a bit of a pain, but not too bad. If your hearing is sensitive, wear ear protection if you plug it in without the battery or test it.

Rated 5.0 out of 5.0 by Great product. Easy to operate. Provides valuable home safety. Not cheap, but high quality by a reputable company. It provides peace of mind in the rare event of CO infusion. Company (Kidde) is a specialist in such alarms and provides excellent quality. September 11, 2012
Rated 5.0 out of 5.0 by Night Hawk CO detector with smoke alarm bonus I have had this CO detector in the past and it lasted ten years without a problem. The batteries install easily which is not true of a lot of CO detectors. I like the digital display. The price was a bargain on line even without the bonus smoke detector. I picked it up at the store. I gave the smoke alarm to my son as I have a hard wired one. October 29, 2013
Rated 5.0 out of 5.0 by No Problems Ordered three. Installed the included batteries, plugged them in and got zeros on the LED readout, which is good. No complaints. The free smoke alarms that come with them are a nice bonus, but I have no need for them right now. Not much more you can say about these devices. October 8, 2013
Rated 5.0 out of 5.0 by Very good deal on a carbon monoxide detector with a digital display This is one of the few detectors on the market with a continuously updating LED display for the amount of carbon monoxide in your room. The First Alert units are actually slightly more accurate according to professional reviews but you have to hit a button to activate the display which turns off after a few seconds. The included smoke alarm to as cheap as you can get, nothing to rave about. August 7, 2013
Rated 5.0 out of 5.0 by Good value and bonus smoke detector included. Very good price with delivery to my home. Peace of mind knowing that I am being protected from carbon monoxide while I sleep. Digital display nice feature. Audible alarm is load too. August 1, 2012
Rated 5.0 out of 5.0 by Like the design and great value Quality product with straight forward set-up instructions; I like the digital read out and constant sensing feature September 18, 2013
