I love the Nest protect, the Gen 2 is fantastic. I have several and they just work, make my life easier and I don’t worry about replacing the battery. Provide a night light and check it’s status via the app.

I carry both the Nest Learning Thermostat (3 years) and the Nest Cam (1 year) in my home so it was not a surprise to pull the trigger on the Nest Protect. Due to the fact that my current fire detectors are wired, I was unsure how to start adding the Nest Protect into the mix. For me, it was decided to replace my current fire detector near the Master Bedroom with the Nest Protect and see how well its integrates into the existing wiring. I also wanted to take advantage of features such as "auto" illuminate when walking by when the lights are off, and the function for Carbon detection closest to the bedroom. The installation was very easy and the instructions made it clear which wires to use and which ones to cap. After installing I ran through a complete Nest Protect test and wow is the alarm loud! The voice is also loud and clear enough to hear for any alerts. After installing, the Nest Protect did not break the connection chain my other alarms still had with each other. My favorite feature, besides life saving alarms and warnings, is the illumination at night. Getting up to grab a drink of water or check on something in the home enables the Nest Protect illumination function to light up my path. It senses my approach, turns on, and fades out as I leave the motion sensor area. It is a great feature outside of its real function (fire/carbon detection). Overall I would highly recommend the Nest Protect and plan to replace my remaining fire alarm devices with this device.

I am sold on these. We had one at our old house and had to get them in or new house. These are easy to set up and manage through the Nest app. They are not to sensitive which helps to eliminate false alarms, and when an alarm goes off the notification is sent. One of the great additional features is the lighted ring that illuminates when you walk past. We have these set up in hallways and it's nice to have a little light at night when hall lights are off. I would highly recommend to anyone looking to looking for a smoke/Carbon Monoxide detector in a smart home setting.

Just finished installing two Nest smoke/Co2 alarms in our home. Before opening the box I felt a little concerned that I might need a pro. Not the case. Very simple straight forward install. Each one took about 10 minutes. It will ask for a test to be sure all is working correctly. Impressed with the night light, and the loud alarm. Once one alarm senses smoke or Co2 all alarms will sound. Great feature for larger homes. False alarms can be quickly turned off with the app.

My family already had one in our main level and wanted to add two more so each level is protected. They installed easily and connected quickly to the Nest app. This product does a great job at keeping us protected. I highly recommend these over your traditional fire alarms.
