(2 pack) Kidde AC Plug-In Carbon Monoxide Detector with Battery Backup, CO Alarm with LED Light Indicators

I wanted a plug in co2 detector for my office and also for traveling. I also needed one I could easily reach when it starts chirpy low battery. This fits all needs. It's easy peasy to open and just plug in since batteries came with it. I wanted one that used replaceable batteries as the sealed type with lithium batteries cannot be replaced and, in my opinion, fail before the 10-year life is up. I wish it was also a smoke detector but it's not.

We needed to replace our two carbon monoxide detectors because they said to after 10 years. Well sure enough, 10 years and two weeks after purchase they needed to be replaced ( it will beep constantly when it's time ). We decided to stay with the same brand because it's been very reliable. We have one in the kitchen because we have a gas cooktop and we have one in the basement for the hot water heater.

As a mom, safety is a top priority—and this Kidde carbon monoxide detector gives me serious peace of mind. I love that it plugs right into any wall outlet, but also has a battery backup so it still works during power outages (which happen a lot during storms where we live). The ease of use is amazing. Assembly takes less than 10 second. We put one in every room in the house even the hallway It was super easy to install—just plug it in and it's ready to go. The digital display is clear and easy to read, and it even shows real-time CO levels, which I really appreciate. The test/reset button is simple to use, and the alarm is loud enough to wake us up if there's ever a danger. Thankfully, we haven't had any issues, but it's comforting knowing this detector is quietly doing its job 24/7. Highly recommend for any home, especially with kids!

Very reasonably priced and highly effective CO alarm. I have purchased several for my rental properties to meet code requirements. I am satisfied and feel confident that my tenants are protected for many years. Exactly the same alarm as those costing 2-3 times as much.

I had a faint chirpping in my house... You know that sound. The sound of something somewhere that chirps every 1 to 3 minutes. Driving me crazy!!! Thought I needed to locate smoke detector. Cleaned all of them dusted with canned air. Come to find out the carbon dioxide detector only lasts 10 years. Check your date on the back. These are easy to use. Comes with one battery. Plug in the wall and pull tab before.

had this same one 10 years ago, and got the 2 beeps that the 10 year life span was over. so I needed a replacement and got the same exact one. this one is in our bed room. We have other Smoke and CO detectors through the house, but wanted this extra one / plug in w/Battery backup for our master bedroom

Since I've only used this product for a couple weeks, and I haven't had a carbon monoxide leak, I can't assess its battery life and performance in an informed way. However, the two-pack was a great price value; the ease of use and setup was outstanding; and the batteries were included and are working. I highly recommend this detector.

Have a home with an older boiler furnace. Having CO detectors is a must. Purchased these given they seemed a good value. so far, so good. Easy to use and set up. Supposed to last 10 years...we will see. I recommend this 2 pack if you have a 2 story home.

I received two separate alarms, not a two pack. They were both in the same shipping envelope. The box one of them came in was heavily damaged and the alarm had obviously been removed, handled, and replaced in the plastic bag it came in. It was dirty and had a small plastic spur on the back broken off. The seller was trying to unload an alarm that had been returned damaged. At the least, this is very shoddy business practice. I expect better treatment.

first of all it was used which was supposed to be new! it doesn't work and it is taking a lifetime to return this!
