The included band was comfortable and secure, but some reviewers found the default/first-party strap options plain or pricey.

battery life
Product 1: Polar Street X
4.5

Battery life is one of the headline strengths, with claims and testing clustering around roughly a week-plus of heavy use or up to 10 days in smartwatch mode.

Product 2: Google Pixel Watch 3
4.5

Battery life was a meaningful improvement, with the 45mm often reaching about two days, while the 41mm remained good rather than class-leading.

3.2

Calorie data was considered useful enough for general training context, but at least one reviewer questioned how accurate the burn estimates felt.

Product 1: Polar Street X
4.2
