Customer Ratings & Reviews

Easy to install using your smartphone. Doubles as smoke detector and carbon monoxide detector. Also has the ability to be used as a motion detecting night light.

I purchased this, after buying several cameras, and wanted to add the convenience of a smoke and carbon monoxide monitoring device, so that I could be notified on the same system as my cameras. I love that this product checks itself every month and is very proactive about keeping you informed.

Let me start by saying I'm a huge fan of Google (probably makes me uncool these days) But I have completely bought into their smart home ecosystem. The last step was adding the smoke and carbon monoxide detector. Twice it lost connection to the nest connect hub which is not even 20 ft away. The only that way I could get it to reconnect was to reset the device and start over. This time it's holding now for over a week so fingers crossed!!! FYI I have a 450 Mbps internet speed that's reliable through my cable provider so that shouldn't be the issue. Everything else in home stays connected. Also, I have no way of knowing if notifications work on my phone or tablet since there's no test for that and I'm assuming I would get notified if my house was burning and I was away, But I also don't know that for sure?!? I thought this would be like all other smart devices and everything would be a notification if I chose. Apparently not. Just trusting no notification is good news doesn't make me feel any better. I've researched after reading the pamphlet and still don't have a clear answer! I bought this for peace of mind when I'm away from home at work or wherever since I have pets and my home is mine biggest investment. Right now it's not providing that since I cannot confirm therefore three stars.

I love all nest products and this is no exception.

Easy to use. It was easy to setup. The app was easy to download and setup. All completed in about 25 minutes.

This level of protection is a must for any household, lights the hallway informs you by sound or cell phone communication on what going on in the home at all times. Works with other devices in the home thermostat ceiling fans etc.

Now have 7 of these throughout the house and love them. The way your about to silence from your phone or even the fact it warms you of smoke first before full on alarm goes off... Definitely makes my dog happier that there is a silent sound check feature.

I am glad that I upgraded the smoke detector to this Nest. It can be controlled from the phone, which is very convenient. I am glad that it has the feature of informing you about what is going on with it even when you are away from home or wherever else you use it. It can connect to Wi-Fi, and you can be notified on your phone through your cellular network, as long as the Nest is connected to Wi-Fi. I just hope that the Energizer Lithium batteries, which are very good batteries, are powerful enough to make it work a long time before they need to be replaced.

I love these smoke detectors. They alert you to any smoke or carbon monoxide, even when you’re away from home. We have one on every level of our home. Highly recommend, along with other components of the Nest system.

This smoke/carbon monoxide detector is a great peace of mind for my family. It even talks. It performs self test and will notify you if there is an issue it works well with all my nest products such as the nest cam and my nest thermostat and it will alert me on my phone or iPad if there is an issue.

I have several of the Protects in my home and I trust that they'll work if the time ever comes. BUT, the one thing that does frustrate me to some level is some of them run through batteries faster than others. I assume it's due to activity, however even when I turn off the night light option it still seems to go thru batteries fast. If I could give it a 4.5 stars I would. It seems too much to knock a whole star. OVERALL, you can't go wrong with them.

It is pricey, but works great and looks beautiful on ceiling.

This is my sixth Nest Protect deployed throughout the home. Setup is very simple...and it is a very reliable product.

After the last of our smoke detectors went bad we decided it was to time to upgrade. Picked up a few of these and the wife set them off the first week lol. More importantly the the last good working detector we had through our alarm company, never made a peep. So yes, well worth the investment.

Still the best product in the nest lineup. Was a bit weird that the white circle in the middle doesn’t share the same nest badging as the others but that is nit picking this thing to death.

I purchased this because I moved into a home that had a smoke alarm probably from the 50's. It was gross and I am sure didn't work. This product looks great and the wireless control from your phone is perfect. It is great to be able to check on the status of your home at any moment.

This item is really high quality. It does not beep for every situation as other regular smoke detectors. Plus Nest test it time after time and notifies you in app about the scheduled testing. I definitely recommend this product.

I got two of these because I was nervous about carbon monoxide, and the current smoke detectors didn't have that feature. This does both, and even speaks to you when it detects something. Very cool.

This is a big upgrade over the old battery powered ceiling smoke detectors. Having alerts sent to my phone if anything goes wrong at home is a huge plus and gives me great peace of mind when I’m away knowing that my house is safe

Highly recommend! We have been using nest sensors for years now and just had to replace our first after 9 years. The app feature is easy to use, alarm self checks and you are able to see status of alarm as well.
