Rated 4.6 out of 5 by 18 reviewers.
Rated 5 out of 5 by CO & Gas Alarm, Digital Readout, It Works CO Alarms are programmed to stop working after 7 years, when their sensors are projected to wear out. That has happened to two of my alarms this year. The new Kidde unit detects CO and gas leaks, so it is better than my old alarms which only detect CO. The digital display gives confidence that it is actually measuring. The package includes a bonus smoke alarm which I don't need, but the price was lower than for the CO-Gas alarm by itself. Home Depot got a special deal and passed on the savings. October 16, 2012
Rated 5 out of 5 by Buy the bundled package and save I picked up this bundled gas detector/smoke alarm at my local HD. I have hard-wired, linked smoke detectors so I really have no use for the little one they throw in the package. Still, this is the only gas detector my HD carried. The manufacturer part number on the alarm is 900-0113, the same as the standalone gas detector here on HD's site for twice the price. Plus, you get a cheapo battery powered smoke detector.

Rated 4 out of 5 by Does the job nicely The Kidde CO/gas alarm is reasonably priced and works fine; plugs directly into an outlet but has a short cord if you need that. Kidde says it will replace a unit that fails within the 7-year expected life span (haven't tested that yet with my previous model which did give out a little early). The extra smoke alarm is a nice bonus. October 16, 2012
Rated 3 out of 5 by Marginal I have purchased and returned 2 of these. I tried to use them with the plug and wire out of the unit (plugged into an outlet 4 or 5 feet from the unit). Each time, the battery goes low in less than 2 days and the unit beeps and displays low battery. I put in a new battery and the same thing happens within 2 days. I continue to use 2 of these with the plug remaining attached within the unit and they work fine. I recommend them only if you can use them plugged directly into an outlet. September 17, 2013
Rated 5 out of 5 by Just what I needed!! Great Value. Would recommend this item to anyone. Couldn't find in the store for some reason so went online and ordered for pickup at the store. Easy and conveinient. December 25, 2012
