Customer Ratings & Reviews

Easy install with all the right tools.would highly recommend.

They are easy to install and compatible with the old Nest detector’s base.

The product just Works as advertised no complaints

Retrofit was a bit longer than expected but overall a great product!

Simple set up and a great way to be able to see what’s happening in your home when you’re away. It connects to non-smart models to let you know when any alarm is going off in your house.

[Employee of bestbuy] Apparently when my house was built, the wiring for the smoke detector was placed in the hallway next to the bathroom. Nearly every time somebody goes in there to take a shower the steam from the bathroom sets off the smoke detector. I wish that I had a way to move the wiring without having to hire an electrician! They really need to set an option in the app to turn down the sensitivity.

Nest version CO monitor expired after 10 year life. Exact replacement with adapter cable to plug into Nest power cable. Simple setup.

I'm sure this smoke and CO detector works well enough for it's intended safety purposes but as far as it being marketed as a Nest Protect replacement it's missing some of the convenience features that were on the Protect due to the lack of a motion sensor. I really miss the path light feature. Also the speaker on this pales on comparison to the Protect. Also it requires another app and account in addition to the google home account.

Fairly easy to replace the Nest sensor we had with the included adapter in the First Alert packaging. Seems to work fine but did have to download and set up an additional app - not a big deal.

The first I purchased had to be returned. The replacement work great as a replacement for Nest. Alarm works with Alexa

Good replacement for 10 year old Nest Protect. Lower quality than Nest product, but simple swap using Nest mounting bracket and wiring adapter.

Good item, purchased a few of them and one had an issue which required a replacement of the item

I was disappointed when google decided to discontinue the Nest Protect. This fit the bill for me as it works with my other nest protects that havent expired and is aesthetically pleasing to me on the ceiling. So far so good!

Love that my phone will give me a notification that my smoke alarm sounded

The product works as intended. However, it’s a significant downgrade from the nest protect. It simply is not as elegant as the nest. Moreover, it has reduced functioning. I do miss nest p.

Very easy install for replacement of Nest Protect.

We love these at both our old house rental and new . Peace of mind

Disappointing--I wanted to replicate the experience of the Google Nests I have had for 10 years which are now discontinued. These were meant to be the true heirs of the Nest alerts but are barely a shadow of them--gone is the motion-activated ring lights we used to light up our dark hallways, the pleasant voice tests, quiet confidence in the combo CO2/smoke detection, and easy to quiet alarms. These First Alert model alerts are loud, obnoxious, and tinny sounding, the lights are hardly controllable, and emit a cold while LED, with a difficult to press silencing button. One of the two I purchased went off falsely TWICE within three weeks (in the early morning, no less) and I have trashed both of them to be sure they never return. And the 10 day return policy passed, so no money back. Garbage.

It’s very new but happy with purchase to date. Phone app is a bonus.

Replaced Nest Protect after it's 10 year lifespan. Simple replacement, even used the Nest's mounting bracket.
