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.
These fit perfectly in my old kidde firex holsters. I thought these were hard wired though so if you’re looking for hard wired don’t purchase these by mistake like I did. But they are still doing their job beautifully and I’m happy with the quality for the bulk price.
I ordered these to replace my old kidde smoke detectors in hopes that they would fit the mount that was already on the wall, and they did. I was not impressed with how long the old ones lasted, and they both died within a few days of each other which makes you wonder. Time will tell how long the new ones last.
