After months of using the Fitbit Charge 3, I can confidently say it's become an essential part of my daily routine. The heart rate tracking is impressively accurate—even during my intense HIIT sessions where my pulse hits 180 bpm. Cross-checking with manual counts, it’s rarely off by more than a few beats.

The sleep analysis feature surprised me with its depth. Seeing my REM cycles and restless moments visualized helped me adjust my bedtime habits. Plus, the silent vibrating alarm is a game-changer for early workouts without disturbing my partner.

Battery life consistently lasts 5-6 days with all features enabled. I’ve made charging part of my Sunday night ritual—plugging it in during dinner so I never miss sleep data. The quick 2-hour full charge means no downtime.

While the default band felt stiff initially, swapping to a magnetic third-party band (especially for swimming) made it disappear on my wrist. Speaking of water resistance—it survived a brutal ocean swim session with waves trying to claim it, emerging fully functional.

The occasional step miscount (like mistaking juice-shaking for walking) is outweighed by clever GPS auto-correction when pushing shopping carts. For $150, this tracker delivers premium features without the smartwatch bulk—perfect for fitness-focused users who want data without distractions.
