## What reviewers say

**Google Nest Learning Thermostat (4th Gen)** — Three whitelisted hands-on reviewers—TechHive, Tom's Guide and TechRadar—tested this exact 4th-gen model and all recommend it. They praise the stunning, art-like redesign with a larger near-borderless display, the smarter weather-aware AI learning with accept/decline schedule suggestions, the glanceable Dynamic Farsight display, and Matter support (Apple Home, Alexa, SmartThings). All three flag the premium ~$280 price. Reviews are largely qualitative—only TechRadar put a number on anything, timing his install at about 15-20 minutes. TechHive still prefers the Ecobee Smart Thermostat Premium. (3 sourced reviews.)
