Customer Ratings & Reviews

I bought two of the Nest Protect 2 on a recommendation for adding smoke/CO detection. Luckily I haven't had any reason to be alerted by them, but having an internet link to be able to see they are always monitoring is a nice piece of mind.

Highly recommended. I was at home and the Nest smoke detector ,detected the presence of carbon monoxide in my home. That alert allowed me to open doors and windows and to vacate my house. It alerted me when levels were back to normal and safe to return.

The day I got a smoke detected alert on my phone I knew I had gotten the right detector. I was in another state, and I knew right away. It turned out to be nothing serious (a hot griddle). Being able to call my wife and find out that everything was ok was fantastic.

It's nice to finally have some control and use coming from our smoke detectors. If someone burns a pizza they don't have to worry about setting off alarms because they can tell the detector it's ok. We also like how it tells us what's going on rather than just making a lot of noise.

It's great that it's a smoke detector and carbon monoxide detector in one. I like the idea of being able to be notified from the app when something wrong is happening. It's also nice you can silence it with the button if it's a false alarm.

Awesome product. Bought four more. Best Buy price matched Amazon. Thank you

Really like the alerts to your phone we tested it and it immediately sent me a message to my phone will be buying again

other than the batteries dying this thing works great, set up was easy, a must have for the CO detector if you have a gas fireplace or furnace.

I installed three of these devices in my home about 2 months ago. Yesterday was the first time that we had an actual alarm. We burned toast in our toaster and all three alarms began alerting us that there was "smoke in the kitchen". Very nice. It really works.

I want to start off by saying that no one NEEDS a smart smoke/CO2 detector. At $100, it is much more expensive than the "dumb" alternatives. However, I recently got one for 25% off and if you already own other smart home items, it can be a welcome addition to your home. It looks good in a modern kitchen but this is one product I hope I don't have to "use" too often. If you need multiple for your home it can be cost prohibitive, but over time, if you find a deal like I did I recommend it for the tech geek in your life.

I love how it updates me when there is a problem but is not like a traditional detector and annoying with every hint of smoke from cooking.

This is one of the best smoke/carbon monoxide detector. It provides very clear setup instructions. One of the best feature is that one can turn off alarm from smart phone. It also sends monthly email about the activity on this Nest Smoke/carbon monoxide detector.

Excellent smart smoke/carbon monoxide alarm. I do like the illumination feature that senses movement at night and lights up the area just enough to see.

Easy to configure and to get it working. Hope will be reliable.

Very easy to install. Incredibly easy setup. Recommended.

great smoke detector. Easy to install in the wall and app in the iPhone. Automatic battery checks are also very convenient.

Works great but for some reason I just set up another home within my Nest account to set up my smoke alarm

It does sound checks often to check if it’s still operable and you can monitor its sound checks in the nest app to check as well. We havent had a fire to put it to the test.

Love being able to set temperature from my phone. Can turn up or down so when I get home house is cozy or cool. Also a definite plus when on vacation. Then monthly reports are helpful too. Our utility bills have dropped since installing.

Google has proven to me that a smart smoke carbon monoxide detector is actually a great thing to have in the house
