Customer Ratings & Reviews

The unit has actually gone off once or twice and is very effective. The nightlight is an added bonus.

I love NEST protect. I have a 15 year old son that was making popcorn in the microwave while he was on his PS4. I was out shopping and I get a text message warning me there is possible smoke in the kitchen before my son at the house even realizes that there is smoke in the kitchen. I have 3 NEST protects in the house now and I am slowly buying more fore each room. They are all synced together and synced to my phone. Can't beat it!!!!!

This is a pretty cool gadget, but a little pricey for what you get. I would like future versions to be able to do more at this price-point. Maybe integrate humidity, temperature, and other air-quality sensors to make it a more comprehensive monitor.

It works well in the house. Good recommendation and love the product since....

Just bought this a few days ago but did give it a tryout. Worked as described.

does the job and helps me ease my mind with the 2-1 feuture

Best smoke detector I have ever seen. connects easily to Nest Thermostat and connect with your smartphone.

Great product so far. Have several nest products. Install is easy and app is great.

Easy to install but I wish I new about the second generation before I bought first gen a while back.

I now have purchased 5 nest detectors. 4 are still in use. I really like the voice announcements that tell the location of the detection...("basement", "Living Room", "Bedroom" etc.). I have found the setup to be less than simple with multiple failures despite being within inches of another device as instructed. one of my detectors failed after 2 years (1st generation). While at work, I got a notification of smoke in my living room. I drove home to find no smoke (and a terrified dog) with the alarm continuing to sound. It was a wired detector that continued to sound after unplugging, due to the batteries. My screwdriver was too big to remove the screws and with the alarm sounding, I could not wait until I found a screw driver to remove the batteries. The only way to silence the alarm was to smash it with a bat. (If I didn't my neighbors would have... 5 detectors were very loud). I can say that they are extremely durable devices. It took many hits to finally silence the device. I strongly recommend using the battery type units over the wired, as this will make removal of the batteries upon failure. I have since found that this can be due to dust build up even though I have always used light compressed air to gently blow the dust and clean as otherwise recommended. I would still purchase another and will soon to complete coverage in all bedrooms only because I already have several nest units. If I were to do it again I would consider a Ring compatible first alert and the Ring alarm system... the final cost would be much less.

I like knowing that my smoke detectors are working properly (thru the app) and it has a 10 year battery life.

This is a great carbon and fire alarm. It is easy to set up and i will be buying more for the house

Set up went smoothly. Testing was straightforward. The connection to my existing app is great.

I love that I can see status via the app and it tests automatically.

Work perfectly, easy to install and has a nice motion light .

This thing knows when I enter the room, the night light comes on and guides me. Love it! Will recommend.

Easy to install, looks good on wall/ceiling. Ties in nicely with the Nest Ecosystem.

Easy set up, works with nest thermostat, and notifies me via app has loud and clear messages.

Great product, gives you peace of mind. The best feature is the night light, no more stumbling at night.

Nest talks to you before sounding the alarm. Easy to control through the app as well. Awesome product.
