Great, sometimes

Great screens, easy to interface with Garmin ANT+, BUT it sometimes refuses to recognize the Garmin, sometimes freezes, sometimes crashes. The GarmimFit app has fewer features but it has never failed to recognize the sensor (even immediately after DigiFit fails to do so). DigiFit Forums seem aware of the problem. (AND these intermittent problems persist after reloading the app, cleaning the contacts on sensor, replacing the battery - waiting 10 secs - trashing and relinking the sensor)
So I got a Polar H7 sensor. DigiFit had no problem pairing with the Polar bluetooth sensor (with the Polar strap or the old Garmin strap).
The DigiFit tracking is still erratic - dropping by 10-15 bpm in the middle of a workout and the bouncing back. Happens every 5 - 10 mins
