    I am not too happy that Nest has decided to withdraw from the market, forcing us to switch to First Alert. After installing the new device, I like its minimalist design. Hope it is a stable one because my previous First Alert non-intelligent smoke detector has "false alarm" frequently.

    I haven't had a fire or CO that I know of to know that it works for sure, but it was easy to set up! The only thing I wish it had was HomeKit integration.

    Easy to install and a good replacement for my Nest Protect that is expiring soon. I was even able to use the Nest Protect bracket to install the First Alert detector. It also works seamlessly with the Google Home App.

    Works but a sad replacement for the nest protect.

    A fine smoke alarm but a mediocre replacement for the nest protect. It is slightly worse than the protect in every way. Worse speakers, no path light, worse app integration and honestly a little bit uglier. Again it works fine but is a bit if a letdown as far as a google sanctioned replacement for the nest protect.

    I bought this to add to my Nest smoke detectors. Was easy to connect to the First Alert app and has no problems staying on my Wi-Fi. I am going to purchase another one for another rental.

    Work well. Same functionality as the Nest protect it replaced. Build quality seems a little lower than the Nest. But still a good product

    Goes offline often

    Installed 3 of these, one on each floor of my house. Easy to add to app and set up. The problem I have is that one of them (the one near by bedroom) keeps going offline. I get an alert about this. I can either get on a ladder and press the button until it gets back online or wait a day while it resolves itself. This happens 1-2x/week and reduces the whole point of them being wired together. If I could stop this from happening, I'd give it a much higher rating.

    Good product, and compatible with Nest hardware (bracket), but does require a new app - won’t connect with Nest - or install of Google Home.

    A little pricier than a regular smoke/carbon monoxide detector, but integrates very nicely into Google home. Worth the extra cost to be able to see the status whether I’m home or away.

    Our Nest Protect expired and they no longer make them. This was recommended as a good replacement. Very easy to set up and install in the same location. Would definitely recommend this product!
