I decided to upgrade smoke/carbon monoxide detector and I opted for this sleek looking wired one. Now I don't have to worry about replacing batteries.

Easy installation of 3 wired detectors. All communicate with each other and provide a clear location alert of troubled area. Motion detection night light was a nice bonus feature.

These are truly and upgrade from the standard detectors - I love the built in nightlight and that you can monitor and control nest devices from one app

Great smoke and carbon monoxide dectector. A little pricy for a dectector. Nice features like the motion sensor with the night light option and the good night glow ring to let you know it is working when turning out the lights. I wish there was a way to get more data from the sensors to monitor trends with in the home. I like that I can link it to other apps in the house as well.

Easy set up. I have a dog at home and I am concerned if ever there is a fire I would like to be alerted as soon as possible. Great pease of mind.

This Nest Protect Smoke Detector is an excellent choice for replacing old wired detectors. It has a battery back up. This Smoke Detector was easy to install and integrate with my other nest products.

I absolutely LOVE my new Google - Nest 2nd Generation Smart Smoke/Carbon Monoxide Word Alarm. It even talks to you. Greatest thing EVER.

Put one in my mom's house so I know when she's burning food. Worried she will burn down the house.

installing this can be a bit of a challenge if you have ancient smoke detectors like I do. I had to cut the wires and strip them to get them to fit into the nest. Also positioning it on the wall and clicking it into place was somewhat of a challenge so you get it straight. Still confused on how I finally got it to be straight. But I like that it lights up when you walk by it.

these are defiantly more expensive but with the nest thermostat the feature integration is great. Smoke will shut off the furnace. Nice piece of mind

This is a 1000x better than your average smoke detector. You can turn off false alarms using your phone, and you don't get that annoying beep when typical detectors run out of batteries.

These are pricey for a smoke + CO detector - but well worth it (especially when your conventional alarm starts beeping at 3am due to low battery power!)

Being able to check status on these things gives me some peace of mind when we're away. Easy setup and installation.

Excellent product and alerts entire home where trouble may be with audible spoken warnings rather than just beeps. Also provides great night light by motion when walking in the dark.

My first replacement nest. My old one expired. Was great for 10years!! Just wish they were maybe 75bucks???

I bought 4 of them at the same time, to replace the smoke detectors that came with the house. They were super easy to install and even came with batteries!

First, stick with the 2nd generation model. Had on for 3 months now and it works as advertised. night light is a good feature and daily self testing is a plus.

Bought three of these when our smoke detectors started going bad. Replace all three in the house and synced them all to my nest thermostat in about 40 minutes. Really easy to use and test.

I was able to connect the old wires strait to the new nest and very happy with the end result. Even lights up my hallway when I'm taking the dog out at night. :)

This is the second one we have trying to replace our old detectors. I like the talking part and the way i set it up where it serves as a night light. Will be buying a few more for the whole house.
