This is Google's new flagship set-top box. It is a sleek box designed to sit on a media console.
Reviewers at Business Insider and Wired highlight the integration of AI, which generates show summaries and custom screensavers. Some long-term reviews from 9to5Google note that while it is faster than the old Chromecast, it isn't "lag-free" and can occasionally lock up during heavy use.
It includes a Find My Remote button on the back, serves as a Matter/Thread smart home hub, and has a built-in Ethernet port for stable 4K streaming.
