Customer Ratings & Reviews

Easy to install, and I love being able to see everything though the Nest app. Night light is actually a nice feature, especially for those who get up in the middle of the night.

So these installed very easily. Instructions were great and very clear. Set up was vice prompted and super simple. I am very happy that I can get a voice prompt instead of a blaring alarm. Also I can check on the status while I am away. The motion activated night light is one of my favorite features.

No more annoying battery alerts at 3am! This has a 10yr battery so it will last a long time without having to be replaced. You can control it over your phone and get alerts. Serves as a nice nightlight as well in kids rooms and hallways.

If you own any Nest products.. especially the thermostat then these are a must have. Being able to talk and turn off your Furnace in the event of carbon or smoke is such a peace of mind. Pulling the trigger on these due to their cost is hard, but super worth the piece of mind.

It is wired, but as long as you can get the part done, it is great. I love how it lights up at night as I walk by it to give me a nightlight on my way to the restroom from the bedroom. It is user friendly.

I have the Nest camera and many other products house so I though that it would be beneficial that i get the Smoke & Carbon Monoxide detectors. The installation was very easy. It really is plug and play. All the detectors come with a 9v battery that is rated to last for years.

It works as described. Easy to set up. No false alarms. Way too expensive for what it is.

Installed these throughout my house after having an issue with "dumb" alarms going off because of low battery when we were out of town, scaring our pets. Neighbor helped make the alarms stop, but being able to control remotely and get alerts on my phone about batteries instead of beeping is great. They auto-test weekly when we are not home. And they are all connected wirelessly (but hard wired for power). In case of a fire, they will also alert you with the name of the room where the CO2 or CO is sensed.

I love these smoke/carbon alarms. They alert you on your phone and you can turn it off if you had something burn in your kitchen. Also, they light up the hallways when you walk pass them in the dark. Like a light up night light!

This smoke alarm is great and was easy to install myself. I like the functionality with the app and being able to quickly silence a false alarm or know if the batteries need to be changed. The nightlight is a nice touch too.

It's a hundred dollar smoke and CO2 detector, but I knew that when I purchased it. The unit works as intended, and I simply want it for the peace of mind through the Nest app, should the alarm go off. Plus, it'll tell you when the power goes out. Installation is simple, but I would recommend a professional install if you've never done anything with your home's circuitry. If this detector cost $75 instead of $100, I wouldn't hesitate to buy two more of them. It's a little pricey, and perhaps a little unnecessary.

It was very easy to install. I have it hard wired in. I love the night light that is has, I bought 2 of these. It's really loud, so I can't miss it. Love that is attached to an app, so I can control it, if I'm not home.

My old smoke detectors were all wired together and one kept setting the rest off. Sometimes in the middle of the night! They needed to replaced anyway so I went with the nest and I love them! No false alarms anymore. Only downside is the price but I feel they are worth every penny.

Have replaced ALL of old style smoke alarms with Nest and will never go back to the old style smoke alarms. Integrates seamlessly into Nest app with thermostats providing the ability to monitor the units at anytime...and there are no beeping alarms in the middle of the night for battery replacement.

Easy to install, great night light feature. I bought these to replace 13 year old fire alarms. These have Co monitoring also. I sleep with complete piece of mibd. They have worked flawlessly. Breeze to hook up to wifi. And it works with your NEST thermostat. How cool is that

I can monitor the thermostat and smoke/CO2 detectors from anywhere via Nest app on my phone. These units last several years and automatically disable themselves once the pre-programmed age limit is reached.

great product. This was a replacement for the same Net alarms I installed 5 years ago. They all need to be replaced exery x years. They worked perfectly with no false alarms. The night light feature is great

Great purchase for people invested in the Nest ecosystem. Nest app gives peace mind with last test details and green ring on hardware is visual piece of mind as well. Lastly, night light is welcoming.

The setup on the first one took a little longer than expected but the second one took 10min. These things also include a night light activated by motion which is extremely helpful in not waking up anyone up. Genius idea and the are loud enough in case of emergency!

A repeat purchase for me. These are great. No guessing about battery life, can be mounted on a wall instead of the ceiling, which makes access easier. Lots of features the old hard wired devices don't have.
