Customer Ratings & Reviews

I purchased 3 NEST Protects for my home and the 1st challenge was seting it up. So hopefully, you understand how your home router works and if it is secure - you have to disable to add the devices. Otherwise, I am very comfortable with its overall performance and its capabilities. You can test it, but only from the home and the night light while not super bright is helpful if it is pitch black once your eyes have adjusted. It really is an improvement over the standard smoke/carbon monoxide detectors I have to admit.

This is a really nice and fancy co & smoke detector. It seems to work great, is smart, and easy to install especially if you already have another nest product (I have the thermostat) and the app is already installed in your phone.

The Nest protect is kinda pricey for a Smoke / CO2 detector, but it is worth every penny. These are simple to setup and install, problem free, and integrate with my Nest thermostat. The pathway lighting is great and it even runs periodic tests on it's own.

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.

Have first generation and have served their useful life. East to install and setup with the app. Gives notice for smoke and CO2. Never had an issue with the first generation unit.

I have 3 of these in my home, they come with batteries and I bought one of these over a year ago and is still working great! I also love the motion light that turns on when it senses motion in the middle of the night!

I replaced 3 smoke detectors in my house with the wired version, and then realized I didn't have one near enough to the kitchen (where, at least in my house, a fire is most likely to originate). Before I had the chance to buy the battery only detector, and install it in the kitchen, my Dogs set a pizza box on fire on top of the stove (It was noticed and put out before any damage was done). The next day I purchased this device and installed it. Now, I get notifications on my phone if someone so much as farts in the kitchen!! (not really, i don't believe it has such capabilities, but you get what i'm saying)

I've always been pleased with Nest products. My review rating is 4 stars ONLY because I have not heard the alarm in action; which, is a great thing! I like how it does self tests, and I can always check on the status of the alarm via the Nest app even away from home. A neat little feature is the "night light" it has when you approach it in the dark; add a little illumination in our hallway.

I now own 5 of these. I started out with one battery operated unit. Now I own one wired unit and four battery operated. Easy to install. Works great. All units work together to warn you when any unit senses something. Works with my Best thermostat.

expensive but seems pretty nifty. I like that it interacts with the app, I would like if they brought back their security system so I could have everything in the same app working together.

Works Great. Has a cool night light feature. Is loud and is smart to work with the nest camera. It's just so darn expensive.

Easy setup, great performance. I like the fact that if one goes off, they all go off. That way if the garage reports a fire, I get an alarm in the bedroom!

Very easy to install, easy to use smoke detector. Like how easy it is connecting to my NEST app. Good piece of mind knowing that I will be notified via my phone if there is any smoke / carbon monoxide in the house.

I bought the wireless Nest Smoke/Carbon Dioxide for my house and liked it so much that I purchased it for my family business as well . It was easy to install and setup . I love the fact that I get an alert on my phone if the alarm is activated .

Having two dogs and two kids- I enjoy knowing things are ok at the house, even when I’m not there. Took me about 2 minutes to attach to the ceiling (better than being on the wall) and less than 5 to set it up From my phone

This is a great product to have in any home. The setup is simple and if you combine this with IFTTT service you can do so much more in terms of functions. Great replacement when you want to swap out an outdated smoke and carbon monoxide detector.

Quick and easy to install. I love that it lights up at night to help you see where you're going. It notifies you instantly when slight smoke is detected in the area and has a very loud alarm to wake you up if a fire occurs while you're sleeping.

Very easy setup and connects right to the nest thermostat. My favorite part is its smoke and carbon monoxide all in one and allows for alerts to come right to your phone/smart device even when you aren't home. Have peace of mind even while you are away.

Works great. This was a replacement for second original purchase. We are now using two new second generation Nest alerts. Should last 10 years before replacement. I.p.o

Works very well! Make sure you read the packaging though. Some have batteries and some are actually wired. Bestbuy doesn't always put the correct items in the right spots and I purchased the wired one first and went back to get the one that has the battery.
