Customer Ratings & Reviews

Nest Protect Smart Smoke/Carbon Monoxide Alarm provides the ultimate protection & peace of mind. The intelligent alerts discriminate between steam and smoke. A clear "Heads Up!" pre-alert gently cautions you in situations when close proximity to steam or a little smoke in the kitchen, for example, is about to trigger an alert. You can silence a false alarm using your phone. Multiple units share alerts to all rooms & to your NEST App on your phone, tablet & computer - so you are protected throughout your home! The "Promise" is a ring of green light that illuminates nightly to let you know everything is good. Walk under NEST at night & the ring glows white, forming a pathlight. During Heads Up, it glows yellow. During an emergency, it glows red. NEST Protect self-tests, alerting you first by the phone app that it will sound. Everything is tested: sensors / voice / siren. Tests are dated & are sent to your app. A monthly summary even shows the exact date & time of each test. This is the premiere smoke detector, able to detect CO2 (even produces a completely different sound, for instant identification). NEST Protect senses both fast and slow burning fires. NO CHIRPS!! This advanced Smoke Alarm eliminates all of the hassles of pesky chirps from low batteries, with super long lasting Lithium Batteries included that last years. Battery alerts are through your App & by voice on the Alarm. To set-up, simply scan the QR Code on the back of the NEST & follow the voice instructions. Easiest set-up ever! NEST Protect earns my highest recommendation - no other Smoke / CO2 Alarm even comes close!

Works great! Easy setup! Test mode is nice! Comes with a night light but doesn’t have much use because you gotta install 12 inches from ceiling to work right.

I lost two birds for Carbon monoxide and smoke buildup at home during winter months . Sensitive product , several times it proved its efficiency. Very easy to install and operate . Happy to have this item at home .

Very easy to setup. Has worked well so far. We really like the night light feature for the path lighting.

I’m so happy that I have this in my home. Piece of mind. So easy to set up.

This purchase was to replace a very old smoke detector in my basement. It was super easy to sync with the other nest detector I have, which I have been very pleased with.

Piece of mind. Calls out locations. I love the motion sensor nightlight as well. Simple to install.

These detectors are awesome, in some rooms I have them set up in another language and others in English. Love the night light feature! Great and easy to install, find location and follow instructions on the app

Awesome product! Super easy to install and the app is amazingly simple to operate!

Easy install, looks good, great connectivity to android

I love these Nest Protects. They are super simple to setup (especially if you already have another Nest Product). They're also very stylish, I think. Very modern looking. Solid and well built. They have an awesome night light that is motion detected. The LED ring changes color based on the situation. The voice audio is great (doesn't sound like a robot). Before buying this, I had 3 others. I've had them for about 3 years. One is hardwired in the hallway. The other two are battery operated in the bedrooms. Thus far, I haven't had to change the batteries. So even with the self checks it does (sound, battery life, etc), they are very low power usage. The other thing I like, is if it detects smoke or CO2, and you have a Nest Thermostate. It will shut off AC/Heat/Fan so as not to circulate or stoke the fire/co2. Pretty cool.

Installed 3 Nest Protects; 1 wired and 2 battery units. Took less than 30 mins total to connect to my wifi and install. All 3 are interconnected over a wireless network and will sound alarms on all units announcing the location and reason for the alert. Also includes a night light feature which can be setup to turn on when motion is detected. Overall a high quality design that interfaces well with the Nest app. The app can be setup to provide notification of alerts and provides status of detector self tests. The wired unit reports status at least once per hour. The battery units report one per day to conserve the battery. No more having to remember when to change the battery as these units report battery status and will warn when the battery needs replacing without the annoying chirps. No false alarms so far.

I have purchased a few of these to protect the whole house. They are great and network between each other so if one alerts they all alert. they also can be accessed online via the Nest Website or app. I like the fact they use long life batteries so you should only need to change them once if at all in the 10 years they are rated to last. Setup was easy and I really like the night light function. They seem expensive but when you start comparing to others with the same functions they are pretty close. They also integrate with the nest thermostat to better tell when you're home or away. Highly recommended!

I have many Nest items including cams, doorbell and thermostats. I have had early devices from Nest and always loved the features, quality, interface and app. When my traditional smoke detectors were well aged, I decided to replace them all with Nest units. They were super easy to install. The battery powered units are nice for putting them where you don’t have wiring. They regularly test themselves and will tell you if you have a problem. These give me peace of mind that if something happens, I will quickly know about it. The battery last a VERY long time and have yet to replace them. They will let me know when it is time. Thankfully, I haven’t had to “use” them but now, even if I am not home, I will know if a problem arises, especially since I have pets that may be at home that cannot call the fire department. Only downside in my opinion is that the are fairly expensive and with Google purchasing Nest, the future isn’t clear. The OG Nest app is far superior to Google Home, but as long as Google keeps improving their Home app, maybe my concern will dissipate.

My existing smoke alarms were well over the "good" date by 10 years when I checked! I knew it was time then to get some replacement detectors as well as an additional unit to cover my basement, where my utilities are, but with no existing protection. Made sence then, to go all in and get a good full spectrum smoke & CO detector for all 3 areas. Also, having them tied into my home network for remote access, was icing on the cake. I bought the 3- pack as it was the right number of detectors AND BestBuy price matched! Can't go wrong!! They were VERY easy to physically install. I was initially skeptical of the included hardware, but it worked perfectly. I was replacing some old First Alert models and the mounting holes don't match up unfortunately. But, it wasn't an issue. You don't need any special tools either; Just a screwdriver. They blend in nicely with the white ceiling which was a pleasant discovery. The app install on my Android based LG G5 went without a hitch and I had all 3 detectors connected in no time. All together, I had all 3 items physically & virtually installed in less than 45 min; from unwrapping the 3pack to walking away. I didn't even have to install batteries, as they came with & installed in each unit. The units self test (or you can have them test themselves via the app) on a schedule and you can view or hear the results. If batteries get low, they literally say that, so you know which one needs batteries. They aren't cheap, but as my & my families lives might literally depend on them, it was a very good investment. These items again, are dual spectrum for smoke AND they also are CO detectors. I really like that they're networked and that they talk when in action. Another handy feature is that at night, they also act as a night light for a few moments when you walk under them. Just for a few seconds, but enough to be helpful. Overall, I'm very pleased with the purchase and whole heartedly recommend them. Check the dates on your current units - did you know they're only practically good for 10 years?? If it's time to replace them, buy these NEST units. If you don't have any in your home, then buy these TODAY! Money well spent, because what is your (or family's) life worth??? When you buy quality, you only cry once.

I recently replaced my 1st gen Protect with this new 2nd gen unit as I'd had them in place for 10 years and CO/Smoke alarms expire within 10 years. I didn't know this, but when 'their time came', the Nest app notified me, along with a really good explanation of why. That's the kind of security I've come to expect with Nest Protects and not only did I replace them, but acquired an additional battery unit for my basement. Now I'm covered on all floors of my home. They're easy to work with and don't go nuts right away when you burn some toast. Easy to test and easy to see if they're working with the 'Nightly Promise' light you'll see when you walk by them. A nonintrusive way of letting you know once a night that they are working. I have to add that I ran my 1st gens for 10 years with a couple of alarms over those years and the batteries were still running strong. Some excellent programming to maximize the battery life while still giving real time alarm results. Something to think about.

I'll admit it up front, I wanted these as much for the 'WOW' factor as the actual function. And these certainly have a lot of WOW. Installation and setup is very simple. attach wall/ceiling plate to surface and then twist sensor into place. Follow the voice prompts for setup and you're done. Really that easy. Now the features. First and foremost it is an excellent fire/smoke/CO detector. I've only had them set off once and that was while cleaning my oven. The cool thing is that it does not just go off immediately, it gives you a voice warning that there is a detection. So if you're cooking and get a warning you can shut it off via the app before you get the alarm. Second WOW feature, no more low battery chirps. It checks it own status daily without any fuss. It will alert you via app that you need to change batteries. I'm sure if you ignore it long enough it will eventually make noise, but why would you? Third WOW feature is the pathlight. If you get up in the middle of the night it will light up the glow ring on the unit so you can see. I love that feature. It is nice when I walk to the kitchen it turns on a light on the way. Same in the hallway to the bathroom. Sure you can buy a $2 nightlight but it's on all the time and not nearly as cool. These are just the most notable and noticeable features. While most more behind-the-scenes they make this the best in class. I didn't even mention how well it looks. Design is elegant yet it blends seamlessly into the rooms. Brilliant.

Pricy compared to the competition, but worth it. Check out the features. Most important to me was the ability to monitor operating condition, battery life and silence false alarms (of which I have had ZERO in the first month of use) from my iPhone. Very easy to install and connect to network/iPhone. Installation would have been even easier if Nest were to provide common connectors to adapt their connector to legacy connections (rather than having to use the wire nuts included) – very small quibble. ALSO – Backplate for the Battery Version does not have predrilled holes to match coming junction box screw holes as in the case for the Wired version. Backplate holes assume installing on a blank surface. Nest should provide same backplate for Battery Version as supplied with Wired Version.

We have 7 of these. Battery operated. We are replacing old smoke detectors (one or two per year). Super easy setup. Also, physically easy to install. With a cordless drill, I think it took me all of 10 mins to install each one. Set took about 5 mins total. Like that they are then linked by smart home Alexa and wireless network. If one goes off, they all go off and tell you where the problem is. Also has carbon monoxide detector. Batteries last ten years and are replaceable. I wish they weren’t so expensive....

At first glance this doesn't look like much...but it affords incredible peace of mind. We have dogs in the house and one fear is that while we are at work our house catches fire and our pets perish. With the notifications to our cell phones this alarm allows us to promptly notify the fire department and potentially save our pets. Our daughters love the night light feature when they get up to use the bathroom in the middle of the night. The way it communicates with our Nest Thermostat is cool too. If it detect CO2...it has the Nest Thermostat turn off the furnace to prevent further CO2 build up. The only issue...is don't place it near the door to your shower. It sometimes mistakes steam with smoke. Not a deal breaker...but a small nuisance. Even with the Steam setting on the alarm.
