Easy to set up and feel secure. No false alarms so far and I like the fact that it illuminates at night serving as night light

I was originally skeptical due to the price, however this is an excellent unit. Very easy to install and setup, I had my entire house ready to go in under an hour with 6 of them. The nightlight is a nice touch!

First and foremost it gives you smoke detector and carbon monoxide protection which has its own color alert and sound. The added benefit I like is that once you register the device onto the Nest app. you can monitor the device online. It has a night light the glows once it senses a moving object. Every activation is logged into the history. Its a nice feature that I used when I was on vacation and I can check to see if the night light activated which it did not. That gives me relief that no one has entered my home.

Easy to install- press a button on the alarm and it runs you thru the process. This wifi option is great as it monitors itself to make sure it is working every day (no loud noises though when doing this). It is smoke and CO2 detector. I have purchased 3 and they all work in tandem. I was sanding near one alarm and it went off (loud noise and voice command). All of the alarms went off so if someone was in another area they would know there were problems somewhere else in the home. Batteries are long lasting so no need to forget to replace them every change in time. Must have for you and your fmaily's safety.

Easy setup, quality construction, works silently in the background checking battery and sensors on a daily basis. Night light is configurable.

I bought a bunch of these to bring my house up to code, along with a couple of the hard-wired version (my house had two hardwired detectors). Setup was a breeze. We already had a Nest thermostat, so the app was ready to go. You just follow the instructions in the app, and each Nest Protect is set up in under a minute. Get them all set up . and installed, then test. The test runs through both the smoke and CO alarms, and because they're interconnected, when one sounds, they all sound. This is especially important to my family...if a fire starts in the basement, we'd like to know about it in our upstairs bedrooms before it becomes a mighty, unescapable blaze. Another cool feature is that the Nest Protect just doesn't give beeps -- it also pulses red and tells you which detector is alerting. You'll hear something like, "Emergency - there's smoke in the basement." So you'll know not only that something may be wrong, but also where the problem is. The Nest Protect works over your wifi and its own built-in wireless connectivity. If there's a fire or other issue and your wifi goes out, the Nest Protect can still communicate with each other. The Nest Protect battery-only and hardwired versions communicate with each other flawlessly, so you can have a mix of battery-only and hardwired. I wound up installing these at my parents' house and brother's family's house as well. One side note too...we have a Ring alarm system, and you can get a Ring smoke/CO listener and place it near any Nest Protect. If the Nest alarm sounds, it'll trip the Ring alarm and notify the fire department.

Very pleased with the Google Nest Smoke Detector! Love the sleek design and the ease of the installation. The combination of the smoke and carbon monoxide detection along with its ability to alert our phone with provides peace of mind.

Great design, excellent functionality, breeze to install. Bought a couple for my parents as well. The 'night light' is a great added bonus.

We had two separate devices for smoke and carbon dioxide. In the middle of the night, we started hearing beeping very 10 seconds or so. The battery was dying and it was very annoying when woke up. We pulled the battery and a week later decided we needed something different with no more late night false alarms. Our solution was the Nest alarm. It tests itself weekly and tells me the results in an app. It also emails both my husband and I. As Nest launches additional devices we’ll be able to add on and control it from the app.

Smoke/CO Monitor. It comes with a bunch of useful features (self-test, warning voice with the location name, night light). It can also be networked, so that any alarm detected by one Protect is broadcast to the others. The Nest app can be used to disable the alarm (useful when away from home). Comes with long-lasting Lithium AA batteries. It is more expensive option though, compared to other basic models available.

Initially grabbed the wrong unit. I wanted a wired version but purchased battery operated one. Best Buy exchanged without issue. Installation was maybe ten minutes. I was replacing a forty year old wired smoke only detector. Unit has a lot of benefits. CO and smoke detection plus at night as you approach the unit the light comes on to light your way. Not a blinding light but enough to help you see in the dark. Highly recommend this unit plus you can pair with multiple units.

I have a Nest thermostat, web cams, Google Home and 2 Protects in my home. They all work fantastic together and all through one app. These were very easy to install and manage through my app. It even will send you a message if it goes off, like when I burn something in the kitchen. An added benefit that I didn't know about this when I bought it is that it has a night light on it. When you walk under it the light will turn on and light up the hallway for you. It is a very dim blue light but is just enough for you to see where you are going at night.

This review assumes that you are familiar with connected home devices and that you are not paranoid about Google spying on you. It is not a commentary or analysis of Google or Nest. I purchase two Nest Protects because I work in a detached office where I have a lot of computers and other electronic equipment connected to multiple extension cords. Deep down, I am always concerned about a fire starting at night or while I am away from home. The Nest Protect is the perfect solution because it will alert you via your smartphone AND it will alert other Nest Protect devices and any devices with a Google Smart home Speaker. By installing another Nest Protect in my house, I will now know if a fire starts in my office while I'm in the house or vice versa. The setup was as easy as any smart home device from Google, Ring, Apple Home Kit, etc. If you have never set up a connected home device, I suggest giving it a shot on your own but have a person who can help you available in case you run into trouble. The Nest Protect is as loud as you'd expect from any other smoke/CO detector. It does not have a microphone in it (to the best of my knowledge), so if you're paranoid about Google listening in, you should be safe. Unless you are using an Android phone. But, that has nothing to do with this product. It works very well with the Google Home app on Android or iPhone. I definitely recommend it over other smart smoke detectors I have researched. However, if you just need a smoke detector and the smart features aren't important to you, I recommend going with a $40-60 dumb alternative.

Once connected a breeze. Installation on iOS not so easy when you already have a Nest thermostat. When you have a Nest thermostat, uninstall this first then install the Protects. When everything is working add back the nest thermostat. If you don’t want monthly automatic tests then turn this feature off. You will also have to turn on the override from app for the alarm, otherwise it defaults to having to push the button on the Protect. Great feature is that you can set the AC to go off automatically in case of excessive smoke or fire. Not sure why google doesn’t have Apple’s convenience for setup.

The detector (mine is battery powered) was simple to install. It connected easily with the Nest app. There are features I did not know were included: 1) a motion detected night light. I did shut that off to save the batteries because it came on each time the cats walked by them. 2) system status light, when you shut all the lights off a light comes on briefly showing you if the alarm is working properly. These plus the other features make the detector well worth the few extra dollars.

These units are perfectly dependable and beautifully designed. They never give us a false alarm and are completely unobtrusive. The most important feature is when connected with a Nest thermostat and CO is detected, it will automatically shut off the furnace. Another surprising feature is their motion-sensitive nightlights. You do not realize how useful they would be. When getting up for a sleep-interrupting bathroom break, the little Nest Protects all glow and light the way. Delightful!

I will start by saying that I am a lover of Nest products. Its design, functionality, durability and efficiency are very good. The price is for me its only point against, but it is very difficult to find something good, beautiful and cheap. This carbon monoxide alarm detector is impressive. It works as expected and also works as a lamp, when the room is dark and detects movement, it emits a blue light that illuminates the road very well. Recommended

Easy out of the box assembly. On install I had other older smoke/carbon ones in place, I simply removed the existing item and template and tucked the wires in, and then placed the Nest Protect hub and its template over the existing template and screwed into the ceiling.

I love these nest protects. they are exceptional quality, super easy to use, and the lithium batteries last years in these. I also like the feature that it auto-tests itself and reports back on any problems. they also tell you when reaching the expiry date. All great features. a bit pricey, but worth it if you can afford it.

This item is amazing,i downloaded the Nest app to my phone and the app shows me that the unit is in good working order, this gives me peace of mind to know that the unit is constantly monitoring itself plus i can also check it.It does a self test daily as well.The feature of the path light on the unit coming on with a soft glow is great as it allows you to see where you are walking without fumbling for the lights.One improvement would be to see the battery life remaining on the app.
