great replacement for nest protect! install is super easy for both wired and batteries models. fits on nest mount with no issues and includes adapters for wired connectors

Very easy to set up. Works like they say it supposed to. I will replace the other one also with the same one.

Easy to install as it has adapter wires for previous nest and the existing holder works with the new detector. I wish though it would light up at night like the old detector

Bought as a replacement for nest protect. Install is fairly simple. However, it is not as feature packed as the nest. May also be a little too pricey but if you are looking to stay with the nest ecosystem, then this is likely your best option

Replacement for the Nest Protect. Works like the other Nest units except for the motio activated night light. Must connect to other nest units using Google instead of the Nest app.

I liked this so much that I ended up buying 2 more. I hope First Alert will listen to their customers, and in the future, add a night light. This is the best smoke and carbon monoxide detector on the market right now.

I was replacing the nest smoke detector that was expiring with this one as the nest is discontinued. With that being said its a good replacement and works with the nest app but it looks and feels a lot cheaper then nest. It also does not have the pathway light that nest does. Again being that i cant get the nest replacement anymore i would definitely buy this again.

Several give false alerts for no reason. Have had to replace 3 of my seven units after only a month

Very easy to install and fully compatible with the NEST device I had.

Very easy installation. I replaced an old First Alert sensor and the replacement was seamless. It looks great too.

I think this is the only game in town as a (discontinued) Nest replacement. It’s an easy install and I’m happy with the purchase.

Quality device and works with Google Home. Easy to add, although you have to add one more app to your phone. Wish it had a spotlight like the Nest App. And be careful to make sure you get the wired or the battery option depending on your need.

Easy install and setup The first alert app is intuitive and easy to use

As Google Nest Protect smoke/co detectors go end-of-life, this is currently the only option for homeowners looking for smart functionality and integration with Google Home. Not going to lie, these are a step backwards from Nest Protect. Build quality, industrial design, and speaker quality is overall inferior while price remains very high. Functionality is fine, but these really make me miss the original Nest Protect and would be more more attractive in the $75 - $99 price range.

replacing one of my nest protects smoke alarms since it expired... this is very easy to setup if you are in this situation since the only thing you have to do is remove the older one from the wire and hook up this new one. You have to have the first alert app (another app!!). But is a painless transition for sure. I tested this new one with the existing ones and communication was perfect.

Packaging was easy to open. Easy to install and replace my existing detector. Instructions and connections to WiFi and the first alert app worked first time. I like seeing check in status in the app

As advertised, this is a great direct replacement for an out-of-service Nest Protect, very easy to plug-and-play if you have the Nest Protect already installed. Once done the Google/Nest app recognizes it and integrates it seamlessly with any other Protects you have.

Solid replacement for your old Google Nest Protect (no longer made). Integrates well with other Google Nest Protects you may still have in your home (i.e. they will talk to each other should you have a smoke or carbon monoxide alert). Works with the Google Home app, after you download and install First Alert app first (2-step process). The voice alerts are a bit muffled compared to the Google Nest Protect, but still quality enough to hear and understand them. I would recommend this item to anyone looking for a plug and play replacement for your old Google Nest Protect.

Easy set up through the First Alert app. Love the fact that you can silence alarm and check the status on your phone. No more waking up in the middle of the night with the annoying chirping when batteries are low.

I was very disappointed when I found out Nest was no longer going to make the smoke detectors. I’ve used for the past 10 years. I was concerned about integrating a new one than working together and would it be as good so far I have to say this is a solid replacement. I’ve had no issues. It’s worked well and I couldn’t be more happy.
