2.7

The included band drew the most criticism in this set, with reviewers calling it dull or overly fiddly rather than premium.

battery life
Product 1: Google Pixel Watch 3

Durability remains a tradeoff: some owners avoided scratches, but others reported scratching and noted the lack of rugged protection.

Product 2: Google Pixel Watch 4
