From The Manufacturer

Google Nest is a smart thermostat that learns what temperatures you like, turns itself down when you’re away and connects to your phone. It has a big, sharp display. And it’s proven to help save energy. In independent studies, the Nest Thermostat saved an average of 10% to 12% on heating bills and 15% on cooling bills. We’ve estimated average savings of $131 to $145 a year.

Expert Reviews

What reviewers liked

The $249 Nest Learning Thermostat has a larger display, a better resolution and a far-field sensor for viewing time and temperature information from a distance. It works with Google Assistant and Alexa -- and Nest *finally* sells a temperature sensor as an optional accessory.
Nest's minimalist design makes it one of the most convenient wireless thermostats we tested. You can select menu items, change preferences and adjust the temperature by turning the device’s outer ring or pressing it to the wall.
You can change all of the same settings in the app from the main thermostat, too. The beautifully smooth interface and the 480 x 480 display looks fantastic.
There are five different color options you can choose from to allow you to pick the best look to match your home and décor. The color options are black, silver, stainless steel, white, or copper.
Remote temperature control
The Auto-Schedule feature did a great job of creating a schedule that followed my daily routine, and the thermostat followed that schedule to a tee. It responded to my Alexa voice commands to raise and lower the heat without fail, and the Farsight feature and large display made it easy to check the thermostat from across a large room.
Learns your behavior, creating automatic heating and cooling schedule

Has password protection to prevent unauthorized changes using the thermostat - app remains fully capable.
The best feature of Farsight, we think, is the capability to choose what the screen displays when it’s not in use: You can opt for the temperature, weather, or time (using a digital or analog clock face), which you can’t do on other Nest models
Offers a compelling combination of DIY-friendliness, sophisticated design, easy-to-use features, and automatic energy-saving settings.
The ring design is a standout, evoking the look and feel of the classic Honeywell thermostat popularized last century. The display is crisp and elegant, and the twist ring comes in seven different colors (you have to make your choice at the time of purchase, you don’t get all 7 rings in the box).
It is a great thermostat because it shows you when you are choosing the best temperature for energy savings. It will feature a little leaf when your temperature is set at an energy-saving temperature. This means that you are saving money and the planet at the same time.
Its exceptional learning ability decreases the time you need to fiddle with temperature adjustment all year long
Installation – of the Google Nest is pretty easy. You can not expect plug an play like with other home tech devices, because you have to connect different wires. But everything is perfectly labelled and described.
Another nice feature is that the current temperature is always displayed in the middle of the thermometer in large digital numbers, so it is easy to see, even for those with vision impairments. And for those who are wary of connecting to the internet, Nest now allows for two-factor authentication through the Nest app so your info will always be protected.
One of the other benefits of the Wi-Fi function with this thermostat is the manufacturer can automatically send software updates as and when they decide to release them which eliminates the need to go hunting for them manually.
This Nest thermostat comes with a number of impressive features. The Safety Temperature Notification alerts users whenever a home is getting too hot or too cold. Filter Reminders alert users to change the filter regularly and keep track of how many hours your system runs so you get accurate measurements.

What reviewers didn't like

The Nest Learning Thermostat isn't compatible with Apple HomeKit.
The company’s two-year warranty is shorter than the industry average.
Nest has a lot of competition now, and the Nest Learning Thermostat 3rd Generation isn’t quite the easy choice that it once was, particularly since there’s no option to expand the system with individual radiator controls.
This product is more expensive than the other options we reviewed.
It still doesn't offer remote room sensors, but it works with numerous third-party devices and supports voice commands via Google Home and Amazon's Alexa voice service.
Notably more expensive than the Thermostat E

May use "power sharing" when connected to a 2 wire system.
One of the priciest models, but its high quality will end up saving you money in the long run.
Herein lies the problem for some users: they find their heat running when it shouldn’t, or the heat never turns back off, or the “pulsing” (as it’s called) damages their system in some way. Every setup is different, but we’ve noticed that the Nest has trouble holding a charge when coupled with an HVAC system that just isn’t run that often.
Even after the initial learning period is over, the Nest sometimes wants to push temperatures that are a few degrees warmer / colder than you’d like
The only problem you may come across with this function is that if you install the device in a place the motion detector won’t notice you, you might find the auto-away setting will activate when you don’t want it to.
Like any other thermostats, this should be located on an inside wall, about five feet up from the floor and must be protected from any liquids or excessive moisture.
