Customer Ratings & Reviews

The smoke/CO detector is great. It even says “goodnight” as it lights-up whenever the lights are turned off by. Illuminating a colored ring and then goes dark. The light is to reassure you that it’s working to protect you.

I purchased this smart smoke/carbon monoxide detector for peace of mine. I feel better knowing my family is protected when at home and my house is protected when we're away. Setup was quick and easy. Testing is easy.

While the directions were very good, the Nest video on YouTube was even better. I followed the video exactly and it worked just as they said. I got the battery powered version so I could mount it wherever I wanted. No issues at all.

They are pricey but they give added piece of mind with the smoke and carbon combo plus they all communicate together. So if smoke is in the kitchen it tells you on all detectors so you know where to go or not go.

This is the second Protect that I have purchased and they work great. I was at work one day and received a notification that there was smoke at home, called my wife and she said that something on the stove burned. Easy set up too.

Very happy with these detectors. We started with two and are thinking of replacing more of our detectors with them. Set up was really easy. I loaded the Nest app on my phone and between the directions in the box and the guidance by the app it was done in a few minutes. My son likes that when he shuts off his light at night the ring glows green briefly to let him know all is good. I didn't like the idea of the auto testing so I shut that feature off but I have run a test manually using the Nest app and it was really easy...just stand near one of the Nest detectors and hit a button and the app tested both of them sequentially and reported back. I really like the idea that I can check the status of them remotely as well. We left our teenage sons home alone for a night and it was comforting to see that I could check on the status of the detectors remotely and know the house wasn't burning down and that I could run a check on them to be sure I wasn't getting a false 'all ok'. I like the fact that the ring will light up white to provide lighting in an emergency as one of them is in an interior hallway where if the power goes out it would be pitch black. We had an older detector in the hallway that also provided a light but it needed replacing and it is challenging to find a smoke + CO detector that will provide emergency lighting. The unit itself is surprisingly attractive. I didn't think we cared about that but as we were installing them it was a pleasant surprise

Works well and sets up very easily. Love the night light feature and the alerts on my cell phone.

If you love tech and don't mind spending the money..then purchase this product...it's no doubt the future...the only con I would have is the price..quite a lot of money to spend on a smoke detector.

Easily set up and easily installed, my 3 detectors immediately synchronized, tested themselves with loud clear verbal sentences, followed by loud piercing alarms. The app works well and allows me to check the status(battery condition) of each detector and to test one or all. The path light feature at night is a nice bonus. These detectors are pricey compared to those of competitors, but appear to be worth every penny, as well as to look better than the competition detectors, which are (relatively speaking) eyesores.

I am so glad that I bought the Google Nest Protect Smart Smoke Alarm

Easy to install, no issues connecting to the Nest app. So far so good.

It works, but a little sensitive. Ran a couple test and went off with steam, and the light smoke from the kitchen. It all depends where you will place it, I do recommend. Love that notifications get sent to your mobile device when it goes off.

When my seven year old Kidde smoke and CO detectors expired I started researching different options and decided to go with Nest. I bought my first Nest Protect on Black Friday. I've been pleasantly surprised on how these normally invisible devices have become the basic foundation of my modern smart home. The pathway lighting is a nice feature as is the Nightly Promise that glows green when you turn off the lights letting you know all is well. I have since added a second device. Integration was seamless as the two devices work together. I will add more as the older units reach their end of life. As an added bonus, If one of the devices detects carbon monoxide it will disable the furnace if a Nest thermostat is on the network. Well done. Simple. Eloquent.

I like that it's not your standard smoke alarm, it has a high tech look and feel to it. I placed it in the hallway so when it's dark you can see the nightlight, which is a cool feature. I will be replacing all of my smoke alarms with these.

I added my new Nest Protect to my Nest account with no problem which I expected. It was easy to configure just like my other Nest products. I have every confidence this combination Smoke & CO sensor/alarm will perform as advertised.

I love the versatility of a single device serving as the smoke and CO2 detector. It was easy to set up and even easier to monitor on my phone whether I am home or away. Definitely recommend!

This was so easy to setup and knowing i'm protected makes me feel save

I've had this unit mounted in the hallway for about a month and a half, and it's worked fine. The motion-activated night light is a neat feature. You can adjust its brightness from the app. The app also lets you know when you last tested the alarm.

As a smoke / C02 detector it does the job very well. As an component to add to a SmartHome the is limited / no support with other SmartHome devices. You may want to have your lights change color or blink when a hazard is found. This will require a 3rd party product, despite the fact that Nest and Google are part of the same family. From repeated attempts to get Nest Support to address this as a consumer issue, they are deaf to these requests from many users. Profile management, if you join other family members it appears that a profile change to alerts impact all users' profiles.

I installed three of these in my new house. They were all easy to install and test. Now I have the reassurance of "smart" detectors that will notify me on my phone if there are any problems and that are all interconnected should an alarm sound.
