Kidde Carbon Monoxide Alarm AC Powered, Plug-In with Battery Backup KN-COB-DP2

I ordered a bolt quantity, for my renters, and Walmart was the only place that could accommodate the amount that I needed and get it shipped in a timely fashion with a decent price!

We all know how important smoke detectors are in our homes. But carbon monoxide alarms are just as important. One thing that makes carbon monoxide poisoning so dangerous is that it is a deadly odorless, colorless gas. This alarm was basically just "plug and play". You just plug it in and it works, testing for carbon monoxide immediately. It has a small green light that lets you know that it is working and that no carbon dioxide has been detected.

Don't know why a product like this wasn't available the first time I bought CO detectors years ago, but it makes sense that they could be plugged in to an existing electrical outlet and have a back-up battery in case the power goes out. The only thing that I think would improve such a product is if it had a ten-year sealed lithium back-up battery installed in it. But, since they are plugged in so low to the floor, replacing the batteries is not much of an inconvenience. This is a definite improvement over the battery-only kind of unit. I think this new unit provides increased peace of mind.

Always a good price and great shipping at Wal-Mart. Time will tell how the product holds up and I hope I don't get to see if it really works as that would mean I have a leak somewhere.

As advertised, very convenient, quick delivery.

small price to pay for security and piece of mind. Carbon Monoxide is a silent killer. Landlord only has one in the laundry room, but I wanted one right near the bedroom and live in an old house. Works as advertised, while I hope to never want to hear the alarms go off, I know I have that added security. 2 year battery back up life and plugs into the outlet.

Lot of research led me to this model. I wanted a plug in. This model has a 10 yr life, uses readily available batteries, will operate for 12 hrs plugged in with low battery, can be set to alarm if inadvertently becomes unplugged. These are all features not available with competitor offerings in this price range. Buying from a supplier with high stock turnover like Walmart is the way to go. Mfg date was 2 mos ago. I bought a different model from a Walmart competitor and it was 3 years old. Battery sounded a low alarm one week after installation. 3 bucks for a 9 V and 4 years life left. Same price for a Kidde that will give me 6 years more life and never need a 3$ battery.

Fire department came and did a safety check and recommended that I can a carbon monoxide alarm and I went with this one. Super easy to install, so far has been no alarm so I assume it is working.

purchased 2 : 1 worked 1 didn't. Problem unit indicated battery failure, but substituted fresh batteries to no avail. Called kiddie rep who determined by plugging in unit and timing chirp response time the unit was, indeed defective. Will be getting a refund, but 50% fail does not bode well for item supposed to guard your safety for 10 years. Wal mart CS was fine. Mailing back for refund.

I purchased the Kidde Model # KN-COB-DP2 assembly # 900-0263 6 months ago for use in my old kitchen with my old gas stove that had major issued with the dials turning off properly. I had a new kitchen installed with new appliances. I went to plug the model back in and the plug in the broke right into the unit. I looked to see if there was any way my husband could fix the plug. This unit is permanently sealed. He cannot look inside to see if he can repair the plug. Will the manufacture send a replacement free of charge? It's brand new? Thank you. Won't allow me to upload photo. Will post on your FB page instead
