Inaccurate distance measured on Smart band

<p>The only reason i purchased the fitness band, was too observe distance covered on my run. On my Saturday run , my running partners Garmin watch measured 10.8km while we did our race, while my VeryFit 2.0 smart band only indicated 7,2km. i noticed this on my very first run already.</p> <p>Very disappointing.</p> <p> </p>
