## What reviewers say

**Fitbit Sense 2** — Three whitelisted reviewers who tested this exact model — Tom's Guide, TechRadar and Digital Trends — all praise its comfort and roughly five-to-six-day battery life. Tom's Guide and TechRadar flag the loss of third-party app support, and TechRadar additionally notes there is no music playback or control. Sensor accuracy is where they diverge: TechRadar found early-workout heart-rate readings unreliable, while Digital Trends judged the sensors to perform admirably. (3 sourced reviews.)
