Customer Ratings & Reviews

Easy to install (how does Google find screws that don't need anchors but hold so well in drywall?) and does exactly what I bought it to do: warn me about smoke and Carbon Monoxide.

This is a fantastic Smoke/Co2 Detector, a must have in any home. If you are already a Nest product user, this goes hand in hand with the other products used to monitor and protect your home. You cannot beat the mobile device notifications. Night light mode is awesome as well!

Great product with excellent connectivity via the Nest app. All alert notifications are sent straight to your phone to keep you up to date on what’s going on at home even if you aren’t there!

Early software versions aside, this has been a dependable and smart addition to my home. I have 3 and plan on adding one more. By far the heads-up warning is my favorite feature. Before an ear-screeching alarm goes off alerting you to how bad a cook you are, the Nest Protect alerts you in a pleasant voice that it has detected smoke and the alarm is about to go off if you don't cancel it.

This alarm is the next generation of alarms. Get notified of any alerts to the phone even if outside the house. Auto monthly check. Comes with 6 super long lasting batteries. Many great features.

I love having Nest Protect in my home. I appreciate that all 3 devices are connected, so when one senses a problem all 3 can alert me. I like that it is connected to the app and my phone, so I can be notified while I am away if there are any issues at home.

I like and feel safer with this connected Smoke and CO2 detector. I like that it is connected to my cell phone. It is also awesome that it talks to you. The handiest feature is the nightlight. It turns on for a few moments at night when you walk by.

Super easy to install, the twisting lock makes it super easy to access the batteries. The pairing for multiple nests was a bit finicky since I had to reset one of them to get them to pair, but they work great now!

The Nest Protect is not a super sexy device, but does everything it is supposed to do. Installation is super easy and is a clean modern looking device. I really like and have benefitted from the automatic light feature when walking under it at night when the lights are all out.

It is really easy to use and set up. Works well with the app and is great that you can use it with just batteries.

Easy to set up and test. The alarm is loud and understandable. There is a difference in alarm between the smoke and CO alarm. The software automatically add te device to the Nest application. Also I like how the device lights up the hallway when i walk through.

Nice smoke alarm. Easy set up, super loud and has a light up feature

Love that this device sends alerts to my iPhone. Game changer and simple. I love it!

MUCH nicer looking, easy to use and easy to understand-- all things you never find with dated CO detectors. All of this holds true for smoke alarm feature, too. Notifies you via smart phone if there's an alarm. Nice!! I truly rest better knowing my kids are protected by Nest.

I love the way these work. The nightlight is good and the verbal warning is very helpful. Reminds my wife to turn on the kitchens stove fan when cooking. I love it. Very easy to install

This might seem pricey for a smoke detector but its worth it. If you have ever set off your alarm because you were cooking something smokey you'll know what a nightmare a standard smoke alarm is. With this one you can just tell it to chill out using the app on your phone/tablet.

Love this as a replacement for the traditional smoke detector. Tested by accident when my steak smoked on the stove and received a warning, easily silenced and received another notice when it detected smoke was clearing. Very happy with this purchase!

Great product and integrates easily with other Nest products. Extremely easy to set up. When I was through I looked back through the instructions to set what I missedbecause it was too easy!

It works, but a little sensitive. Ran a couple test and went off with steam, and the light smoke from the kitchen. It all depends where you will place it, I do recommend. Love that notifications get sent to your mobile device when it goes off.

Love that there’s an app for these. So many great features. Easy to install and get up and running. Would definitely recommend to anyone.
