This is a great, sturdy smoke detector for larger rooms in our house. It's easy to install. Batteries included! I'm glad I purchased this! Also, glad there is a smaller version for our smaller rooms. When we moved into this home, the smoke detectors were over 10 years old & they were beeping incessantly because the batteries were low. They left wires dangling from the ceiling when we had to remove them. After installing this a couple of months ago, I can tell this is a quality product! Of course, it's nice to have peace of mind for our safety! I'm purchasing another one for our hallway, and I have recommended this brand of smoke detector to my family members for their homes.

I got it as replacement for Kidde hardwired alarm which started beeping because of the aged battery and was glad that this new one fit in the old base. It saves a lot of work and possibility of ruining the ceiling. Since it works on ordinary AA batteries, it’s easier to maintain.

The Kidde Smoke Detector with AA battery power is a great choice for simple and effective smoke detection. It’s easy to install and the battery-powered design ensures that it will work even during power outages. I appreciate the LED warning light indicators that let me know the status of the detector, providing extra reassurance. The alarm is loud enough to be heard throughout the house, offering reliable protection. The battery lasts a long time, and the unit is compact, so it doesn’t take up much space on the ceiling. Overall, this smoke detector provides peace of mind with its reliable performance and user-friendly features.

I like these smoke detectors, in general, as they do not react to cooking odors, However, the level of the actual alarm leaves something to be better desired. It is just not up to what level I expect an alarm level to be,.. to get a person's FULL ATTENTION!!...but at least I don't have any more false alarms from cooking vapors any more. THAT is a DEFINITE PLUS for this unit

This smoke detector caught my attention because it comes from a reputable and long-established brand, and the lightning deal made it an easy choice. I bought two units, with one intended to replace an old detector that came with the house and was likely over 25 years old. As most people know, smoke detectors have a recommended lifespan, and it’s important not to exceed it for safety reasons. Generally, it’s advised to replace them every 10 years or so. Installing the mounting plate was very straightforward and only took a minute using the included screws. After that, you simply insert the detector into the mount and twist it to secure it in place. It’s a very simple process. While cooking, I accidentally set off the new smoke alarm, which suggests it’s more sensitive than the old one I replaced. Overall, I’m pleased with its performance, as it provides reassurance that it’s working effectively and keeping us safe.
