Customer Ratings & Reviews

We have kids afraid of the noise and chirping the regular detectors make. These are smart connected to my phone and we replaced all of our old style with these.

Better than any other detector and alarm. Doesn't freak you out with loud noise. It sends you message on the phone and tells you with pleasant voice of the problem and that alarm will sound.

We needed some new smoke detectors in the house. Decided to get the combo because heard great things about it & wanted an updated carbon monoxide one. Absolutely love this one. It talks to you & works great!

This was an addition for my laundry room. I have over ten of these in my home and am very happy with them. Worth the money for the piece of mind.

Don't think twice about buying one of these. This is a must-have a very household, they communicate between them and send notifications to your phone

No much to say, since it's just there and you don't really interact with it. it's a smoke/co2 alarm. If you have a nest thermostat then it's natural to add this to the eco system.

As we have only had the smoke detector for a month there is not much to say. It looks nice an the instructions were clear enough. We have it installed and haven't had any issues.

Must have it, peace of mind for your family. I love it, it monitors smoke and carbon monoxide inside the home, sends messages to my phone with updates if there is a problem.

I accidently left something on the stove and it boiled dry. The alarm immediately notified me on my phone that smoke was detected. I was able to easily take care of the problem.

I added this as a way to help reduce my health insurance. On top of that I tested this out with my bad cooking...works great!!

Every smoke alarm should come with an LED flashlight built into it, like this product has. I know it seems like an expensive smoke alarm, but I highly recommend it.

Easy Setup but integration a pain. Migrating from Nest to Google Home or Alexa is very cumbersome on standalone setups. The device itself works great

Very smart and intuitive, and easy to setup. If you can get them on sale, then it's worth the price. Lots of cool features that integrate with other Nest products. I wish they doubled as a Home speaker, though... seems like an easy feature to add. Make sure you use the recommend batteries, or it'll fly through other batteries.

works well i have it in my basement. i have other nest products and the app is easy to use

Very easy setup you only need WIFI. Make sure you have good WIFI in all of the areas the connection doesn't seem to great when I put one in my basement.

The device does the job it intends but does it smarter. Love the night light feature.

I bought this for my son for his apartment at college. It is a great product and allows him to monitor what's up in his home without being there. Get a camera as well and you can monitor everything.

Could be better for the price!!!!!!!!!!!!!!!!!!!!!
