Customer Ratings & Reviews

It went off once when there was an electric fire in my room. I put out the fire with my extinguisher. I wish it would come in a package deal with an extinguisher. I like that it calls my room the master bedroom when it is not. I like that it has the night light and you an adjust to low, medium or the brightest setting and all from your phone.

Love this unit! Needed to replace an old smoke detector that kept misinterpreting steam from the shower as smoke. This unit knows the difference and does not go off when my wife takes a long hot shower. Also really like that it does its own monthly alarm check! Battery life is great, lasts a year or so.

Expensive, yes. All Nest items are. BUT this thing is solid. It's well-built, the lights on these alarms are cute and provide a good visual feedback on the state of the fire alarm. They test regularly, and the software on the iPhone app is super solid. MOST importantly, however: it works great and detects smoke readily. When one alarm goes off, the others do, too. So if you're upstairs and there's smoke in the kitchen, every one of these alarms will geneate a audible voice message saying that there's smoke. I wish they were more affordable, but wouldn't buy any other brand as far as I can tell.

Easy to install. Work great. I like the light on feature when you walk by.

Easy to install, setup, and use. Enjoy not having my old alarm set off false alams calling the fire department to our house. I will always use something like this from now on.

Simple device that does what it says (within reason). Painless install that works with Mesh Networks finally! The only issue is a max of 10 homes in Google Nest so if your using this for many locations (or in a small business application) be aware of Googles limitstions

It is not often that someone would get over a Smart Smoke/Carbon Monoxide Alarm but this cool piece of technology is just amazing. Three things that might not be obvious that I really like. 1) super easy to install and properly configure, 2) Technology that makes this thing super smart while staying reliable, 3) Nest simply exceeds expectations. Super good reliability, quality and it is just smart where it needs to be.

Easy to install and super easy to use. Smartest choice in smoke alarms

Easy setup And love the nightlight feature , returned since really need wired

I already own Nest thermostat, so I already have a nest account and it is easy to add products to the nest account. I just replaced the existing smoke alarm with this one in few minutes. The instructions are very clear and the customer report is world class. You can monitor the status using Nest app or you can easily integrate with smart hub like Wink or smartthings in no time. Overall, very happy with the product.

Easy to install. Beautiful to look at it. The functionality online is great. Nest is simply fantastic.

This is awesome! It's very sensitive. Let's me know when dinners ready, but unlike other smoke detectors it can easily be silenced so you don't have to rip it off the wall and take the batteries out when there's burnt food in the oven. The nightlight is another awesome feature that is very handy especially since I work nights and get home in the dark. I can know my home is safe when I'm away by looking on my phone. Love it!

easy to set up, control from your phone, connected while you are away.

No annoying low battery alerts (the loud alarm sound that doesn’t stop in cheaper alarms) are not a problem. Easy install, I’d recommend borrowing a drill with a 5/64 drill bit to make it easier to put the screws into your ceiling or wall

I purchased a pair of these to complement the other smoke alarms (basic) installed at my home. Easy installation, but make sure to understand where to place them. They communictate with each other in the event of an alarm. Nice to have for piece of mind, especially if you have natural gas coming into your home.

Really like this Smoke Detector, last very long on AAs batteries and sensitive enough to detect smoke and Co2, pair to the nest Apps to keep connected, no matter where you are. Wifi connection and colorful lighting. The chirping is real loud and alert on your phone as well.

So far so good, easy to install, nice looking, night light feature nice

Easy to install. No Problems. Works great. I like the night light and the green status light ( lets you know it's working). I must admit I feel safer going to bed with these smoke/carbon detectors. I plan to add to more rooms

Easy installation and integration with Nest Thermostat. Planning on adding additional units.

I've used the Nest Protect Smoke/CO^2 alarms for over 7 years. They interconnect nicely and intercom to all the units if there is an alert such as "Heads up, There is smoke in the basement". These are supposed to connect to the Nest Thermostat and turn off the furnace if CO^2 is detected.
