Customer Ratings & Reviews

We're so glad we bought these. They work perfectly. We have four in our house and they all speak to each other flawlessly. You can schedule them to do checks whenever you want. If you want to replace your old ones. Highly recommend.

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.

Love that you can be notified through nest app and have that piece of mind!!

I was impressed at how easy this was to set up and so far have been pleased with it performance. Being a smoke and CO2 detector, I hope to never have to "use" the product. The status indicator is nice and the path light is a neat option that helps when walking down a dark hall at night.

These work seamlessly with a Google Nest setup. They self check and report out through the app. I feel confident that these will do their job if ever needed. I also like having remote access to their status via the app. Good purchase.

Smoke Detector works and looks great. The only frustration is the Nest products can be difficult at times to attach to your network. I have found if I reset my router after every Nest product added it seems to work.

I have replaced 2 regular smoke detectors for these that also check for carbon monoxide. They work in conjunction with the Nest Thermostat to keep you secure in case of a fire or gas leak. These are a security items every home should have.

Bought this for basement and 2nd floor. Love how they communicate with each other. If the basement nest sounds it will also make the second floor nest sound alerting me if any possible hazard.

I have three of the Nest Smoke and CO Detectors and I'm definitely buying more in the future. It brings a new modern way to protect your home and they are so much better than the old crappy smoke detectors. They have many great features and the app works really well.

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

Bought two of these NEST for my elderly mother, who is in the process of selling her primary home. We can monitor her home while she is away for peace of mind. We also purchased two CANARY video products to monitor her home along with the NEST, again for her POM and for her home security.

We have two of these and they work well with our nest thermostats and lifx bulbs. The battery notification is worth the price. Even when you regularly schedule battery change outs on old school detectors I still found myself searching the house at 3am for the chirping. No more!

I went simply looking to upgrade to a "smart" smoke detector and ended up beginning my connected home experience. Great product with tons of potential.

I've had this product for a few months now and I want to finish buying more for my house. It does everything it says and I've tested it with a smoke can and it shut off my furnace and notifies me. I linked it to my Lifx lights and all my lights in the house flash red. Great product

I mean don't you want a smoke/carbon detector that alerts you even when you're not at home ? The only annoying thing is it wants to randomly test the speakers and announcements. Great other then that !

I bought the smoke alarm for my parents house located 700 miles from me. I have made their house into a "smart" house for my benefit because I live so far away and worry about them. The products was easy to install and easy to coordinate with the other Nest products.

After purchasing my NEST Thermostat, I had to purchase a NEST Smart Smoke/Carbon Monoxide Alarm. I chose the battery-powered version, but it also comes in a AC Powered version. If I'm away, and a problem occurs, I'll be notified on my smartphone. I recommend this to anyone.

I bought 2 battery and 2 wired versions to replace older ones in my home and love the features so far. It's nice to hear a voice response instead of just a horn sound. Also I love every how it integrates with the whole home automation program. Worth the money so far.

This is so much better than the traditional smoke/carbon monoxide alarms. It sends an alert to my phone if there's smoke, so even if I'm not home I can protect my house. It takes a moment to set it up, but it's well worth it.

What a great product. Any time it is about to go off it alerts you so you have the option to stop it in advance. It connects to my phone so I get alerts. I recommend this product
