Google Nest Thermostat, $84.99 (Was $129.99)

Google’s Nest Thermostat is a particularly good Prime Day deal because it can actually help pay for itself over time. The Wi-Fi-enabled thermostat can learn your habits and schedule over time, and activate your HVAC (Heating, Ventilation, and Air Conditioning) system more efficiently and less frequently. Running these power-hungry appliances can help lower your utility bill over time. The Nest Thermostat’s best feature is its easy to understand user interface. Touch-sensitive strips on the sides allow you to raise and lower your home’s temperature with a swipe, while its clear face displays your current and set temperatures. You can also control the smart thermostat using an app on your iOS or Android device, or using the Google Assistant or Amazon Alexa smart home assistants.

Need a bit more pep in your step each morning? Don’t skip this deal on De’Longhi’s 37 Ounce Bar Pump Espresso and Cappuccino Machine. You can use this machine to make espresso (single or double shot), cappuccino, or latte drinks. A manual milk frother will allow you to get that barista-style finish on the top of your drink, too. The machine’s Rapid Cappuccino System allows you to make drinks back to back without having to wait for water to get back up to temperature. If you’d like to move from coffee pods to fresh grounds, this is the machine to get.

Why Trust Popular Science

Popular Science started writing about technology more than 150 years ago. There was no such thing as “gadget writing” when we published our first issue in 1872, but if there was, our mission to demystify the world of innovation for everyday readers means we would have been all over it. Here in the present, PopSci is fully committed to helping readers navigate the increasingly intimidating array of devices on the market right now.

Our writers and editors have combined decades of experience covering and reviewing consumer electronics. We each have our own obsessive specialties—from high-end audio to video games to cameras and beyond—but when we’re reviewing devices outside of our immediate wheelhouses, we do our best to seek out trustworthy voices and opinions to help guide people to the very best recommendations. We know we don’t know everything, but we’re excited to live through the analysis paralysis that internet shopping can spur so readers don’t have to.
