GPS accuracy is excellent. In a 10K run test, the Pro X2’s track matched a Garmin Forerunner 255 within a 2% distance variance, making it highly reliable for runners and cyclists who need precise distance and route mapping.
Battery life diminishes significantly under GPS load. With 4 hours of GPS runs, sleep tracking, and constant HR monitoring, the battery dropped from 100% to 34% in just 3 days, falling short of the 7-day standard use claim.
The optical heart rate sensor shows minor lag during high-intensity intervals. It delayed by approximately 3 seconds compared to a chest strap, which may affect real-time zone data for interval training but is acceptable for most users.
It’s generally comfortable with a lightweight (42g) build and breathable strap. However, the sensor bump can leave a slight indentation on the wrist after more than 8 hours of continuous wear.
