Rated 5 out of 5 by from Outstanding Product We integrated our Protect into an extensive remodel in which all the existing CO and smoke detectors were replaced. The physical design is pleasing and the interface with the app and humans has been flawless so far. I particularly like the night light feature and the pre-alarm voice alerts. Our licensed electrician wired the system, but I installed the Protect. Pretty simple and pretty great.

Rated 5 out of 5 by from Very happy with the Nest Protect This is a great unit. I purchased the battery operated version because I didn't have access to power where I wanted to install it. It's great that Nest offers both a battery and a wired version. Installation was very easy and the mobile app is great. Only downside is that it has a 10 year life and you have to replace it at that time. Hopefully Nest will offer a trade in allowance in 10 years.

Rated 5 out of 5 by from Nest Protect Literally saved our lives! It detected CO from a faulty water heater and passed word along each of the connected Protects, alerting everybody throughout the house. As each detector measured elevated levels, they continued to give status updates. The old “working” CO detectors were still in place and did not function. The app and all other Nest products worked in perfect harmony. Thanks Nest!

Rated 5 out of 5 by from Great Wish it connected to older system I am sold on the Nest family of products and love their ability to show me data when I am not home. This was a very simple rewire for me on an existing Smoke Detector location. The only issue I has was that my upstairs system has 3 smoke detectors that were connected via a 3rd wire so that if 1 went off, they all went off. I wish Nest would incorporate so I don't have to replace all detectors.
