The Kidde KN-COSM-IBA smoke and carbon monoxide alarm is a quality alarm. It is easy to install and use. It works well and the instructions are easy to understand. The alarm is a must have safety feature in any home. I would highly recommend this product. I received this product complimentary in exchange for my honest review. These thoughts are of my own and have not been swayed.

It was very easy to replace the old existing Kidde alarm. I didn't even need to replace the mounting plate. It took me under the 5 minutes to install. I really like that the battery compartment is on the front of the unit, which makes it even easier to use. Hope that the EOL would be really 10 years as specified. Overall, I am pleased with this Kidde Smoke/CO Detector alarm and would recommend it.

This is now the third or fouth Kidde smoke alarm that we've had. In fact, I used this one to replace a carbon monoxide detector in our hallway. I love that this is both a smoke alarm and a carbon monoxide alarm. It's easy to install and makes me feel safe knowing it's installed.

This unit replaced a Kidde smoke detector that was probably over 15 years old. The installation was very simple and everything you need is included. I really like having one unit that is both a smoke and carbon monoxide detector. This unit also has the ability to interconnect with other units like it, so that when one detector is triggered, all of the units announce the alarm. My house is small enough that we only need one unit but if you have a second story, I think this is a great feature to keep your whole family safe no matter where they are. Since our previous unit was so old, I had no idea that the newer units use spoken voice to plus an alarm to warn you if fire or carbon monoxide is detected, I really like that feature. There is a quick silencer button for when I'm cooking and smoke gets in the kitchen and I need to silence the alarm. It also tells you if the battery is low instead of chirping like our old unit. It is recommended to replace your smoke detector at least every 10 years so I'm really happy to have found this Kidde unit that is both a smoke and carbon monoxide detector in one.

This is convenient, a smoke detector and carbon monoxide detector in one. It feels quality made and the instructions are easy to follow. We tested the smoke detector and It's very loud. We will definitely wake up if it goes off. I wasn't able to test the Carbon Monoxide Detector. I'm pleased with this purchase.
