Customer Ratings & Reviews

This is my third Nest Smart Detector - this one replacing my original one that was almost 6 years old. The first one worked like a charm - no more annoying beeping at 2am when the battery started to get old. These detectors actually talk to you and let you know if their battery is nearing time for replacement. You will also get an alert on your smart phone if the alarm goes off when you are not at home, informing you of a potential problem. These work well with other Google/Nest devices and integrate well into a smart home environment.

First our entire house has switched over to Nest products. We have been very happy. We have total of 7 in our house. A nice feature is the night light option for night. Wasn't expecting it. As I stood and vaped below the detector and blew my vape upwards and looking at the Nest alarm, within seconds trouble was indicated, all activated and cleared themselves in 12 seconds. Within the 12 seconds, we both received push notifications of the activation and the an ALL CLEAR. Highly recommend. Also, don't buy them one at time. They have three and six packs for cheaper. Just look for them. Also make sure you have the correct ones. Battery or wired. Enjoy

Nothing else really like it out there - both C2O and smoke detector easy to install and set up. Bonus is automatic night light when it senses that your there. Only complaint is the price.

I feel this is the best carbon monoxide detector in the market. It was easy to setup & sync to my phone. It also great that it has a motion detector & doubles as a nightlight.

No more waking up in the middle of the night to the beeping of a dead battery in a smoke detector and trying to figure out which one it is half asleep. We bought these to replace all of our smoke detectors in our house. They alert all phones set up letting you know if there is smoke in your house (and specifically which area of your house) as well they do their own test and will count down so that when they start beeping you are aware it’s coming (you set this schedule up in your app). They also make a great little nightlight for when you get up in the dark. And they dual as carbon monoxide detectors as an added bonus.

This one isn’t cheap, but is much nicer than other units out there and I love the connectivity to my phone. Super easy installation, they obviously are making a quality product here.

We’ve replaced nearly all of our smoke detectors with these. They’re easy to install and being able to check them thru the app is great.

Looks Great - mount fit into existing box and was easy to install and connect. Night Light is helpful and its not overly sensitive.

Easy to install and use... keeps my family safe!! The price is a little elevated for the things that it does considering there are other products with the same characteristics and cost less

I have had a few cooking mishaps (burning the food in the pan). This device was great at detecting smoke before ti was too bad and providing a warning. Then after a point sounding the alarm. I am thankful that I am able to turn it off through the app as it is rather high up. Also works well with the nest cameras so that when an alarm sounds there is an automatic clip generated for later review. I like that the device preforms sound checks itself to ensure that it is still functioning as intended. The status light that turns on when the lights are turned off is helpful in pointing out problems (i.e. with Wi-Fi). Though the in the dark walking light could be brighter.

Install was very quick and straight forward. Just disconnect the old and replace with the Nest Protect. Love the night light feature and self diags. light, when you turn off your lights.

We’ve had our best thermostats and nest protect for about 4 months now. For me it was a great purchase. The thermostats are amazing and have already dropped our electric bills as they continue to learn and adapt to our heating/ac schedule. We’ll see how it does now that it’s getting colder. The nest protect has been great as well. I like the updated technology and the daily self checks. We love the automatic nightlight feature that senses you approaching and turns on. The aesthetics are modern and pleasing to the eye vs the traditional smoke detectors and bulky co detectors. Being able to control everything from my phone is a major plus.

Good product. Very easy to install. Light your path at night is a cool feature.

I like that it works very well and integrates with other nest products (I have nest thermostat) and sends notification on phone. However, it still gets lot of alarms as it is very sensitive, especially in kitchen. I wish it send alarm when it is real smoke vs. cooking. Argument can go other way too that you invest in something that really catches something faster.

I purchased this product because I wanted to ensure that if there was an incident at home while I was not there that my pets would be ok, and I would be able to reach out to the fire department. I love that it give you a verbal warning before it is about to go off, and that it self tests. I like that you are able to check up on its status from your phone, and i have it linked to work with my Alexa. The feature that i like most is that it acts like a night light, and the ring will change from green to white when you walk by so that you are not bumping into things. Its a small feature, but it makes me smile everytime it happens.

Easy install - automatically detects/coordinates other units in home. Pathway lighting feature is very useful at night!

I've purchased 3 of these Wired Nest Protect alarms for my new house and to replace generic wired smoke alarms of unknown age. The Nest Protect is easy to install and monitors Carbon Monoxide and Smoke. Several reviews online indicate that this device performs measurements more frequently than other devices. Nest provides a website and cellular phone application that allows review of system performance. For example, if there is a power outage, it identifies this in the application. The interconnection between Next Protect units is via WiFi. It does not include a wire to for a wired interconnect. I do not know if units interconnect with lack of WiFi.

It's quite nice unit with fire and carbon monoxide sensor + night light path with motion sensor. Easy to install and sync with wireless Internet. Sensor and battery life is good for 10 years.

Great smoke detector. I like that this smoke alarm self tests and connects to your phone, however it is pricey.

These detectors are amazing - they talk, tell you what its happening and where, can light up to show you your walkway, and integrate well with other devices. You can even see a history of when there has been movement in the room (cat locked in somewhere?). We have 9 of them - installed the original version years ago. And over the last 6 months each of the original ones has died, but after 7 years or so I can't say that is surprising. Having demonstrated them to my in-laws, they are now in their hose too, as well as our ski condo.
