Because it says Nest Protect, I assumed it was a Google product and got a bit frustrated in the installation process when I scanned the QR code using the Nest app to add it to my list of other Google/Nest products. But then I open the installation guide and there the solution was, I just need to download the First Alert app. Once I did that, the process of adding them with my other Google products and the physical install was indeed simple, each taking about six minutes to install and setup.
I opted for the battery version over the hard wired option, for two reasons:
1. I live in a home already built (meaning the walls are all closed up)
2. It's a lot more flexible and convenient to install

If this smoke detector is the replacement for the Nest product, you couldn’t use the same brackets … i only chose this brand because First Alet took over Nest … now i have to remove the Nest brackets and re-install the First Alert brackets.
