What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 3 lab-tested.)
Praised: Comfortable to wear for long periods; Long battery life, roughly five to six days between charges; Strong health tracking, continuous EDA stress sensor plus ECG.
Flagged: No third-party app support; Always-on display roughly halves battery to 2.5-4 days; No music playback or control.
