Kidde Carbon Monoxide Detector, Plug-In with 9V Battery Backup, Digital Display, 85 dB Alarm, LED Status Light Indicators, 3rd Edition

Upon recommendation for ability, and the fact our current CO detector is pushing seven during renovations. It attaches to the ceiling. Figured replacement early based on quality of function for new device and huge savings to buy two as singles if worth it. As vintage ceiling tile are being installed and this device is flexible as to where it sets up. Can be plugged in with the back up battery or wall mounted with battery alone. Although it’s a bit large has a keen sense of detection. There’s no price or device size that matters with safety. But if ya can score a discount kudos. No matter what detector you buy make sure it has a digital read on how much CO2 is invading when it does. To know what’s safe … 0 😁 all seriousness, under 30. The booklet explains the levels. How the device will function in a warning situation. Symptoms o look out for. How long it’ll take to read CO2 depending on how severe it is. It’s recommended to take one on trips when staying at hotels and this detector is easy to set up anywhere. The two pronged action is helpful since this vintage house has a mix of two and three. But for a trip the 9 volt battery is good to go. For RVers this is a must have. Even in a van camping. Better to be safe than sorry. Tip: Write the date of install in permanent marker on the face. This way no need to remember. Tip 2: Same with smoke and fire detectors. For those , what I do is write the yr and month the battery is changed every time. Thin permanent marker should leave plenty of room. Unless hardwired and in ten you just emplacements it. Still, add the date of install. Same with fire extinguishers. Doesn’t hurt to have the fire department inspect it periodically. I know people who’ve lost their hem to fire. Not fun. I know people, like myself, a CO detector got us outta the house. What I like about this detector is the directions have great specifics for set up to avoid false positives and a freak out. Yeah, I did. It was scary. Thank goodness the two times it was for real we were safe. Though at that time we didn’t have a level readout. That’s what makes this gem such a peace. Not sure how long the sale is for. But the singles are a great price now. Hope you score a savings, too. Hope I never hear these defectors go off. But I feel save knowing new ones are in place every ten or less years, if your renovating, where to restock 😊

Quality Kidde brand CO detector. I replaced my original one with this identical one after 10 years of service, when it finally beeped and showed "END" in the display, which renders it useless, which is by design. Ironically, I never had any CO issues or alerts, until about a few months before its 10th anniversary in service. My home's natural gas boiler was over 25 years old, and begin leaking CO from incomplete combustion issues. This Kidde CO detector audibly alerted me and displayed the current CO level as well as the maximum CO level that it had recorded. Very simple to use and displays basic, yet useful information. I was able to open the windows and ventilate my house to prevent the excess CO buildup from harming us, thanks to this CO detectors audible & visual alerts. Hope they're still making this model 10 years from now, when I will need another one, or if I decide to move and want to purchase a new one. It's certainly not the cheapest CO unit on the market, but it's a good value for the money. Oh, it plugs directly into any standard 110-volt power outlet and it has a 9-volt battery backup, battery included. Although they recommend you replace the 9V backup battery every few years, I never replaced mine, and it was still almost as good as the day it was installed. My Kidde CO detector is plugged into an outlet in our upstairs hallway just outside of our bedroom. Fortunately, it also fit perfectly next to (below) my plug-in doorbell, which was a huge plus! I'm planning on installing one in the basement, near the gas boiler as well. Should have done that years ago, as we would have likely received an earlier "heads-up" that there was a combustion problem with the boiler. One last note: You can remote wall-mount this unit also. Cool feature! If you look at the last picture that I posted with this review, you can see that when the rear access cover is removed to access the backup battery, there is extra cord stored on the opposite side of the battery. The connected main power source plug can be easily removed and relocated/extended, via the corded connection, in order to have the CO detector located somewhere other than directly plugged into the power source. There is also a handy little clear plastic packet included, containing two wood/mounting screws and two wall mount plastic expanding inserts. (Not shown in picture.) Just can't say enough good stuff about this unit. Very pleased with it!

I bought this Kidde carbon monoxide detector because my wife is pregnant, and getting ready for a baby has made me think a lot more about safety around the house. I wanted something simple, reliable, and with a digital display so I could actually see readings instead of just relying on an alarm. Setup was straightforward — plugged it in, installed the backup battery, and it was ready in minutes. I like that it has a digital screen and peak level button since it gives more information than basic detectors. The battery backup is also reassuring in case power goes out. The size is reasonable and it doesn’t stick way out from the wall. Alarm volume seems loud enough to hear throughout the house. I can’t speak to long-term durability yet, but first impressions are positive. If you want a straightforward carbon monoxide detector with a display and battery backup, this seems like a solid option.

I needed this for a rental property that we are selling. It provides both battery backup as well as plug in power. It is easy to operate, inexpensive and does the job.

We just pluged it in and it was ready to use. We feel confident that our family has chosen a great carbon monoxide detector for our home.

Worked very well

After researching, I bought this detector because it detects much smaller amounts of carbon monoxide than most of the others I looked at. According to industry standards, this brand is recognized as the best on the market. The only draw back; It's so heavy, that it leans away from the wall, where it's plugged into an electrical outlet. To solve this, I put some duct tape behind the unit, to hold it to the outlet cover. Now it stays against the wall, without leaning away from it. A good quality product, and not to obtrusive.

I have a boiler in one of the bed rooms so thought it was important to have a good alarm .put battery in plugged it in .Reading came up as "0".The next morning it did intermittent bleep I went to check it the battery was flat the plug was red hot ,fire hazard so I sent it back cost me £12.75 to send it to Spain !!!
