Customer Ratings & Reviews

I bought the Nest Thermostat 3rd generation and installed that first. After returning to the store, I saw this device and was intrigued, so I did a little more research. The draw for me was the smart features of this device that enable it to send notifications to your smart device if issues occur. For me, I feel reassured when I am away from home for extended periods knowing that the device will notify me of any disturbances. Also, like other Nest products, this device takes 5-10minutes to setup.

Easy to install and set up. Do like the night light!

I bought this for my upstairs. I had recently bought the nest thermostat too. So I wanted to keep everything with the same app so I wouldn’t have a bunch of apps for smart home things. The setup was very easy. It does weekly sound checks and sends notifications to you if there is any issues or alarms. After having it for a week I went out and bought another one for my basement. I highly recommend this product.

Easy to install. Has night light feature (if desired) and can run self checks periodically. I can also monitor from my phone!

In turning my home into a smart home on the Google ecosystem, this was probably the easiest item to set up. I chose the battery operated one and was simple install both on the ceiling but also within the app. It constantly does self checks and keeps me posted if something is irregular. Highly recommend this product as well as the Google/Nest smart home products.

Haven’t had any issue so can’t tell a legit review BUT the lights at night are pretty cool when you walk by and connection to phone is seamless and simple.

Great product very easy to install and set up. See everything from app. Very safe product price is totally worth it

Robust functionality, easy installation and setup and integration with other NEST Protect and Thermostat

Very simple to set up. Love that it talks to me and that it lights our hallway at night with a motion detection night light.

I own six of these, and I have to say this is one of the best smoke detectors carbon dioxide detectors that I have ever owned. You can set them up on your phone. It does not charge you. The alerts will sound at the unit and on your phone if there is an issue. It also does manual checks on it every day to make sure they are working, which is a beautiful feature to have, so actually, your product is working. If you look in the news every year, so many people die from home fires and gas leaks, and if they would have a decent smoke detector in their house, they would be alive 

Very satisfied with the NEST smart home CO/fire detector. Easy set up using iPhone app which walks you through the entire process. Nice app interface showing current status and test results from each day. App can be used to test and silence the alarms in addition to sending a warning to the phone if the alarm is sounding while you're away. A great feature that my family really likes on this Gen 2 model is the Pathlight which is a motion activated nightlight that illuminates the area when someone walks by.

We like the safety it provides to our home. It was simple to install and has worked flawlessly and the night light is pretty cool

These are great alarms. Very solid, dependable, integrate well with other Nest Protect alarms in a large house. Note that I actually wanted the wired version, but they've been sold out for months, it's not clear if the wired version is coming back. Delivery (when it shown) is currently May of 2025.

As with most Nest/Google products the set up was quick and easy. Yes almost every other smoke/CO2 detector is cheaper but since I have many other Nest/Google products it integrates with the Home and has away from home access. We have animals and if the CO2 gets high it shuts the Nest thermostat off and notifies the cell and gives the heads up to get them out...

This unit was easy to setup and install. The light path feature at night is awesome

Love it and its connected to my app with all my nest products

I love having everything connected and being able to check from my phone. No issues. Easy to set up and install.

I bought 2 of these to go with my Nest Thermostats. Install both physically and wirelessly were smooth. No problems, up and running on both of them within 15 minutes. Status has never been an issue and they have never disconnected from the network. Mobile alerts are awesome and the ability to shut them down remotely is a great feature. No more ladders needed. Also the alert between real smoke and steam is a great addition. Expensive but worth it.

I have builder grade Kidde Smoke Alarms in my house. Even after replacing the batteries every year they never fail to go off in the middle of the night. I have been replacing them with these Nest units when that happens. They are an easy install and provide great piece of mind! They even function as a pathlight when it is dark and everything is controllable from an app on your phone or tablet.

Easy to install, looks great, and the nightlight feature makes it more than just a detector.
