What reviewers say

Reviewers agree it is Google's best smartwatch yet, with a new larger size, a brighter screen with slimmer bezels, useful sleep, wellness and running insights and no paywall for key scores. The common criticism is short battery life on the 41 mm model; The Verge found it works best with a Pixel phone, and TechRadar disliked the unchanged band mechanism.
