Reviewers praise
- Bright, vivid AMOLED display with excellent outdoor visibility and minimal gap between glass and panel
- Offline topographic maps with generous storage and simple drag-and-drop download
- Lightweight aluminium case with slim profile and quick-release standard bands
Reviewers push back
- Wrist-based heart rate sensor struggles with interval efforts, shows delay in detecting rate changes, and performs poorly compared to older Polar models
- Battery life is erratic and inconsistent, sometimes lasting days and other times draining rapidly with identical usage
- Screen wake gesture requires exaggerated wrist flicks and fails reliably on smaller wrists
“they really hit it out of the park with this display”
