Customer Ratings & Reviews

Bought this to integrate with other (non-Nest or WiFi) detectors in the house but there is no third wire. Otherwise, easy setup and reliable.

Links right up to your Nest with ease. Gotta get one.

I got the wired option. It was easy to install and working well. Particularly like the fact that it self test and I will not need to replace for 10 years.

Has nice features can get alerts through your cell phone with the nest app. Voice alerts as well. More expensive than traditional smoke / CO2 detectors

Love nest products and among them, the smoke/carbon monoxide alarms are some of my favorites. You get much peace of mind by having these and always having access to the data from your phone. I highly recommend these!

Bought two of these to replace my old ones after buying a thermostat. Wiring is well explained and syncing was a breeze. Like how if it detects carbon monoxide it automatically tells the thermostat to shut off. Like how it senses when someone is walking by so it'll light up the walkway. Great product overall.

WISH THEY LASTED 20 YEARS... OLD ONE ONLY LASTED 5.. WHEN THEY GO OUT.. THEY GO OUT AT 3AM IN THE DEAD OF NIGHT BEFORE A BIG VACATION.. SUPER ANNOYING.. BUT GREAT PRODUCT! THAT COULD SAVE YOUR LIFE SO THERE IS AN UPSIDE

Works great. Love that a night light comes on with motion detection. A nice added feature I feel safe knowing that my nest protect is on and functioning.

Nest products are always expensive but they last longer and well build. Nest protect 2nd gen also expensive but safety is more important than money. After I installed 2 of them; one for downstairs and one for upstairs I feel more comfortable. I can sleep better because I know Nest will protect me and my family.

If you have a nest thermostat they are great since they all are in the same eco system. Is it worth the money over a standard fire/smoke detector? Probably not, but for the techy person or someone crating a smart home they are great to have!

Love these. Awesome interface, spoken commands and announcements. Replaced the 1st generation unit. I hope it speaks in 10 years during the day that it's time for replacement, instead of beeping wildly at 3 am like the 1st gen did...

I decided to swap out my existing detector because the Nest Protect integrates well with my other smart home products. I also like it's illumination when motion is detected so that at night it helps when kids wake up. The installation is a cinch so long as one has the appropriate tools. Set up is also a cinch.

This is a great smoke detector it hooks up easily.

Nice product from Nest, as usual. Easy to pair with phone and wi-fi if you already have other Nest alarms installed. Supply seems to be short when I went back to buy more of these.

this is a perfect smoke alarm this is the 2nd one I purchased as I have fairly high ceilings in living room and master bedroom - hard to change batteries at 12 feet, I highly recommend it well worth the cost.

Like all Nest products this one works great. It has a very human like voice to warn you of smoke in the room and assume will do the same for carbon. It checks itself monthly, one word of caution is that it works with your home wi-fi and if you loose your internet connection it will disconnect.

Setup was a little difficult at first...but once I got started it went smooth. 5 units installed, works with my Nest thermostat/Nest app. Replaced existing “wired” smoke detectors....no more dead 9v batteries beeping in the middle of the night.

This smoke detector does an amazing job of notifying you if there is smoke or carbon monoxide present. In addition, it also notifies you when the power goes out which is a nice feature if you are not home. I highly recommend this smoke detector especially for the automated features. I own 6 of them.

I bought this for my townhouse and am very happy with the devices. I did have some major issues setting up the connection via wifi and had to call Nest for help, a first. To date, 2 months, no issue with connections and am able to not only control the smoke alarm but also able to control my thermostats.

We replaced 6 smoke alarms with the Nest. We have 4 in our summer home and because of the ability to use our smart phones, we can constantly be aware of whats going on in our home when we are not there. They talk to us, and they talk to each other to check and make sure they are working together. Great product.
