Customer Ratings & Reviews

Easy to install and setup. Works great! Love the night light feature for the kids rooms.

The install on the smoke and carbon monoxide detector was simple to wire in I also like to feature that's on the phone I can see which one's going off also they do a monthly test on each other to make sure they're working properly and they have path lights that you're able to adjust if you want them on or not so when you walk by they'll turn on and illuminates the walkway

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. Had to swap this for the battery-powered version. Be careful-- there is very little difference in the packaging.

I LOVE THIS PRODUCT. EASY INSTALL. EASY SET UP. LOVE THE NIGHT LIGHT FEATURE!!!!

Worth the price. No longer need to worry about wondering when detector fails. Best yet the ease to silence false alarms. No more quickly fanning and opening doors to silence the alarm. As simple as how fast you can unlock your phone and open the nest app.

It's good peace of mind to have a smart monitor like this. It self tests, so I don't have to worry that it's not going to work when I need it. It will alert us to any problems when it does the self check, which I think is a great feature. I also like that it has a gentle illumination that will come on when walk nearby at night... makes a perfect night light.

These smoke/carbon monoxide detectors are excellent and easy to setup. If you have more than one they all connect together so if one goes off they all do

This is a very nice smoke detector. I got the non-battery version. It was easy to plug into my home's electrical connection where the previous smoke detector was installed. I had some smoke go into it to test the smoke detector, it worked well but I expected to get an immediate alert on my cell phone. It took quite a while to get the alert on my phone and I only saw it after going into the nest app. I have my iphone set to allow notifications from the nest app so I don't know what the problem is. It defeats the purpose of getting an internet connected smoke detector. I need to try again some other day. I would still recommend this product since it is almost perfect.

The device is easy to setup and test. Good look and feel

After seven years, the builder installed interconnected smoke/carbon monoxide dectectors died because of their end of life expectancy. So we purchased three of these Nest Protect 2nd Generation Smart Smoke/Carbon Monoxide Wired Alarms. The install was super easy and the app is great for home and away. We then upgraded the remaining with three more - all six are now interconnected.

This is our 3rd one in the house. Works great with the app. The night light motion at night is a really nice feature too. Worth the money

Bought two of them and was impressed with how easy they are to install and how efficient they work. Had a little smoke from cooking over the holidays and the alert was loud and clear advising that there may be smoke in the area. It gave a verbal warning and if it had been more smoke it would have alarmed. Great product which could ultimately save lives especially from carbon monoxide.

I bought two of these for my house. They are simple to install and set up. Once you connect them with the app and internet they will work as one unit. If smoke or carbon monoxide triggers on the other will automatically alert you. You get notifications on your phone once connected to the app, gives me a sense of security knowing if I'm not home I'll get a alert of what is going on

I have been gradually replacing the wired smoke detectors in our home with the nest protect co/smoke detectors and the price usually doesn’t change. They are usually $119.00 each and Best Buy had a special for 2 for $199.00. I bought 4 at this price! Thanks Best Buy! Super easy to install and setup!

Easy to install and work great. It's great to have a smoke/CO detector when you're home. This takes it a step further and will notify you via the app when smoke/CO or even a power outage is occurring. I've replaced all the old detectors in my house with them.

Love these little guys. Just like how they have the night light option as well as giving you an verbale cue on what room is having the issue etc.

This is an excellent smoke detector. It has already shown itself to be much less likely to throw off false alarms. I love that I can remotely check on it and that it does self test regularly, rather than just hoping that plastic box on my ceiling will work if there is a fire, or excess CO2. The only thing I would like to see is HomeKit compatibility, but you can't have everything.

I had to have an electrician install this but it’s great. It’s easy to set up and the mobile app communicates in real time. Perfect for people who are deaf or hard of hearing. The phone chimes but so does the unit when you’re in the house. It will state where the problem is beforehand. Awesome technology!

These have been great. We bought them to replace similar devices from another brand that were literally a nightmare. I wish I had bought these to begin with.

Easy to install by cutting the hard wire smoke detector wiring in your house, use wire nuts on the unneeded wires and wire nut the black to the Google smike detector. Very easy setup, love the night light feature and it will self test daily at a time or your choosing. Only downside is it does not integrate with the Google home app, you have to use the Nest app and the Nest app alone. Other than that slight, yet irritating fault, I still think these are awesome!
