Customer Ratings & Reviews

First, stick with the 2nd generation model. Had on for 3 months now and it works as advertised. night light is a good feature and daily self testing is a plus.

Excellent product and alerts entire home where trouble may be with audible spoken warnings rather than just beeps. Also provides great night light by motion when walking in the dark.

Sharp and crisp co / smoke detector. Love how it turns into a night light which is quite convenient where I installed it in my hallway.

I was able to connect the old wires strait to the new nest and very happy with the end result. Even lights up my hallway when I'm taking the dog out at night. :)

Easy to I stall and very nice decor. I tried the smoke alarm to see how it would respond. Very loud and also turned on.ky nest cam and sent me a notice.

This is the best smoke detector on the market! I have three of them and love how they monitor battery life, sound and update you through the app.

Bought three of these when our smoke detectors started going bad. Replace all three in the house and synced them all to my nest thermostat in about 40 minutes. Really easy to use and test.

Love how it connects with others in house and the rest will alarm when one goes off to alert of emergency elsewhere

This is the second one we have trying to replace our old detectors. I like the talking part and the way i set it up where it serves as a night light. Will be buying a few more for the whole house.

Now have 2 thermostats and 4 smoke/carbon monoxide detectors installed in my house. I installed and it was very easy, good directions and a pretty simple process. They look great.

Great product. I feel better knowing what could happen with my dogs at the house while I'm at work and that I'll be alerted. Easy to set up.

Great smoke detector . Huge bonus you can assign a time to be informed about the battery being low. Not 2 am when most Batteries die. Fantastic!

Replaced whole house with the nest protect and couldn't be happier. Very easy to set up and I can see if my house is safe through the easy to use app.

I love the fact that this smoke alarm also has the Carbon Monoxide monitoring built in. I think it is definitely worth the price if you need that feature. I also like the night light feature.

Working great easy installation easy operation with app

Extremely easy to install and set up. The App is very fluid and easy to use as well. Product works great and feel safe knowing that if we had an issue this device would alert me in many different ways!

Nest doesn't disappoint with this. Took longer to figure out what circuit my hardwired alarms needed to be turned off. Seamless fit, nightlight motion feature is awesome.

New to Nest products and this device works great, better than the house smoke detectors. Love that it lights up when your walking in the dark past it. Would highly recommend!!

Easy to install and a great networked system. Make sure you install the app so you have warning on the few times that it will test throughout the year if you are home

I recently purchased the Nest Protect dual carbon monoxide and smoke alarm detector to install in my home and it works seamlessly. I have it connected to my Nest thermostat and WiFi.
