Customer Ratings & Reviews

Easy to install and run the initial tests. Can't really assess more than that unless it is is ever actually needed in an emergency

Haven’t had a fire, but seems to be working well.:)

This is a great addition to home security - you get fire, CO2 and a friendly path light. The app keeps you in full contact with the home system -- can add onto system as well. Can't say enough about having a low dim light when you come close -- and the happy green light saying all is well when I am ready to head to sleep for the night.

Our smoke detector was old (they have a 10 year life) and our carbon monoxide needed to be replaced as well. One Smart device for about the price of two. It's great to be able to monitor the situation at home. We loved it loved it so much we bought the thermostat & security cameras a few weeks later. All were easy to install and set up.

This is a great product that makes me feel safe at home.

Easy to install as it does not require wiring. Great smart home choice. Can not speak about battery and longevity as I have had this for only few weeks now. But I loved it so far

This best device is great I have multiple of them in my hosue and works well. If you are not home you can get alerts to your phone to know if something is wrong

This smoke detector is awesome easy to set up and works great

The Nest Smoke/Carbon Monoxide Alarm is very cool and brings a lot of comfort knowing your home is protected. I like the idea I will get notified on my phone should an event happen. Had the Geek Squad install and they were awesome.

Smoke/carbon monoxide easy to install and monitor.

It's to set up and use. It's priced very well for the value.

Excellent smoke alarm. Replaced all the wired ones with these and added a few battery ones where I didn’t want to add wiring.

Easy to setup, great directions, very loud, I got 2 love them

The Nest protect works great and was simple to install.

Great product was very easy to setup in my home!!!

The self test works. It recognized the other smoke detector with no problems. It is the basement so no experience with kitchen odors or smoke.

Nice upgrade and combines smoke detector and carbon monoxide detector in 1. Linking units (bought 5) together took a little bit, but eventually worked. 4 stars because Nest has not figured out how to have these units communicate with your monitoring service. In other words if there is a fire the units will not contact fire dept, you better be near your phone to receive alert and call yourself. Nest brochure says every second counts because your home can burn down in under 10-minutes yet no way to connect these to your alarm system.

Great purchase and really happy with the performance.

We love the simplicity and design. It functions well.

Really like this product. Everything we wanted. Recommend.
