Smart features can be a bit flaky but the heart monitor is awesome and very accurate.

The features work, most of the time.

The track back feature gives me peace of mind when I'm running a new trail alone, that if I get lost, it will always bring me back to where I started

Great watch with fantastic features for running

My phone was off 450m on the same run)Also, since the GPS is so good, the instant pace is also great (not as great as with a footpod but comparing to other gps units is way above)The watch has good amount of customization and shows really solid info on the watch itself after a workout
