Customer Ratings & Reviews

I’m a techie and this combo detector is amazing. Very loud. Battery and hardwire. Easy to mount. Night light when it’s dark and senses movement.

People will argue that is expensive for what it does but it is so easy to install and gives the protection needed. It integrates easily with my connected house. a No brainer

Nest continues to be some of my favorite smart devices in my home. Easy install, easy use. Cannot recommend enough.

My first thought was "why would I pay this much when I can get a non-connected one a lot cheaper?". In less than two months it has alerted me twice. Both valid alerts (new stove - Turbo boil is really hot). I like the fact that it will turn off my HVAC unit when an alert detected and that it will notify my Nest thermostat that I am home. (It sees me more than the thermostat) the night light is a nice feature. And the monthly tests are reassuring. When was the last time you checked your smoke alarms? My old ones were way out of date!

These smoke detectors are the best. I feel extra safe knowing we have these in our home. I love that I will receive notifications on my phone and know I can leave my house and feel confident that these will inform me of any issues. I can also go on the app at anytime and check the status. It does checks automatically to ensure that they are working properly. I also like that they will still work if there is a power outage.

Install is simple - both the manual install and networking/adding to the app (we have two pre-existing Nest thermostats). The guide lights at night are a neat added touch and are customizable (on/off, light intensity). The pre-notification on the app for the smoke alarm works well and requires more than just a tap to turn off, which is a smart design. Overall, happy with the purchase.

So far so good with these. Using them with a Starling Home Hub so they work with Apple HomeKit. Installed them myself to replace existing smoke alarms. Installation was simple; just 2 wires to connect.

Enjoy being able to add these to our Nest smart home. Easy to set up, install not hard if you are any what handy. Have not had any issues with them yet.

Had this for a month now. I like it. It works as advertised, and I could see how integrating it with other Nest products would make it even better. Moreover, installation was easy (I purchased the wired model). Still, the $100 price point is a little high, when you figure you can buy a good (albeit traditional) CO/smoke detector for less than $20.

The product has been great so far. Physical installation was SUPER easy but WiFi setup was a huge pain!!! Once I got past that it's worked fine. While it's A bit on the expensive side, it does have some cool features like the path light that illuminates when it senses you walking by at night. I like the peace of mind that it checks itself daily.

Bought 4 of these to replace the "dumb" wired ones I had from 2012. They picked right up on my Wifi, Synced with my Nest account seamlessly. After a few personal tweaks with the guidelights and testing. They went right up easy. As expected for a Nest device, painless and just work. I am very pleased. In situations with multiple units, follow the wiring. These have 2 wires and instruct to remove the third. This all could vary on your installation of course. Do your research.

Love it. Easy to install. I bought 3, one for each floor of our house. Love that they all connect. Night light is nice too.

Great product, easy to install! Love the pathway light that comes on in the dark automatically. I am not a fan of the Nest thermostat, but these units I would recommend.

Easy install and intuitive setup! Was easy to retrofit to my current system of home protection.

Bought this product after seeing that you should replace your detector every ten years. It is an easy install and connected with no problem. Lets hope it never alarms.

Easy to install as a replacement for previous wired smoke detector. connected to app right away and app works well to monitor status.

Great product! East to install and love the functionality of it. Especially the night light that comes on as we walk through the house.

Bought 2 for house. Easy to use with app. Nightlight is pretty neat. Easy to check settings/info on app!

Great design and easy to insatall but may be over price

The Nest Alarm is head and shoulders above the competition: better quality construction, easy set up, easy integration and superior protection.
