Customer Ratings & Reviews

the night light feature probably gets used the most, and i didn't think i would need it but it has been handy. the fact that your phone gets notified if the alarm goes off is a nice peace of mind as well, along with the voice confirmation of the alarm so your not left wondering what the chirp means.

Had heard mixed reviews about the gen 1 Nest Fire Alarms due to false alarms/glitches but read solid reviews about gen 2. I can honestly say after a few months in use these are worth every penny! Everything from aesthetics to functionality, technology, and design make this a top notch product.

Easy to install and the monthly test and report is a great feature to let you know everything is up and running.

I have been using the Nest Protect wired for 4 years now and needed to add one in my garage. They work well really well. Easy to setup, status light and options in the app help cater it towards your needs.

I was using an older smoke detector, and another carbon monoxide detector. This next protect does both on a single device. I was able to use the existing mount to install this which made everyone fast and simple. Highly recommend this.

I like how easy it was to configure the Nest CO2 / Smoke detector and how it looks in my house. I used my iPad to set it up and now I can feel safe knowing that my family is protected from both fire and CO2. I am going to pickup a 2nd Nest CO2 / Smoke detector the next time I am in the Best Buy store.

I needed to replace my 20 year old smoke detectors and wanted something that I could monitor and be more updated than my old unit. It's easy to hook up and set up. I will be buying another one soon.

Installation was simple and it does what it's supposed to do. Traditional smoke alarms are useless when you're not home. We have pets so I love knowing that they are safe when were away. There are plenty of other great features that this product has, but peace of mind is why I bought it.

This newer generation now has a lifespan of 10 years. An improvement from the previous generation. Connects up with other NEST protects. Too bad it doesn't communicate and send alerts via Alexa. No surprise I guess.

This smoke/carbon monoxide detector is very cool and nice to look at. You can tell it is a quality product once you start to open the package. Was extremely easy to install and looks great on the wall. It's almost fun to have an alert!

I like these alarms (see review for battery version). This one is wired to 110v and we have the nightlight option turned on. It is very helpful at night. Do not use that feature in a bedroom though as it turns on every time you move!

The Nest keeps you up to date on each system evaluation it does. At night, it lets you know it is working with a quick green glow. It doubles as a nightlight when movement is detected. Overall, the Nest does more than expected and those little things make the price worth it.

I ordered 6 Nest Protects to set up in my house. I was able to easily connect these devices to my wifi using the phone app. I did need to rewire the ceiling connection but the part was included in the box. It had the entire house finished in less than 2 hours.

Love these Nest smoke/carbon monoxide detectors. For the last couple years I have had the battery version of these due to me renting an apartment and I didn't want to permanently attach them by removing the current wired ones. However I just moved into a new house and replaced every single wired smoke detector with these. I love how I can control from my phone to silence them in case I burn something in the kitchen. I also love how they integrate into my other Nest products like if one senses smoke it turns the HVAC off to keep from spreading the smoke around. It is also nice to know these self test multiple times a month to ensure they are always working correctly. It would be nice in maybe a future version Nest incorporates an air quality sensor in each unit to make them even smarter but who knows if they will. I love these units and they are so much better than the standard smoke detector in everyones home.

Connected to nest easily, works as should and has a nice nightlight feature as well!

[Employee of bestbuy] Seems to be pretty reliable, set up was easy and device is sleek looking. Over all nice product

These are great if you already have wired smoke detectors in your house. It lets you monitor your home from anywhere, and you can even just add one of these to your existing setup and it will work flawlessly with the existing dumb smoke detectors.

Best combination smoke detector and carbon monoxide detector on the market. Full functioned, smart device with good connectivity. We have basic First Alert smoke detectors (hardwired and interconnected) for the bedrooms and have the Nest unit as an independent device in the hallway.

I love these Nest protects. They have an option for a night light and senses and records any motion events. They are also excellent smoke & CO detectors. They will test themselves on a regular basis and work together with other protects if there is an incident.

I think I prefer the battery one over the wired version. It's a smoke detector. Everyone should have one. I like it because it doesn't freak my kids out. It also talks before it starts screaming out smoke alarm.
