I've got a Garmin 620 and I'm quite keen to purchase a decent sleep tracking, step counting activity tracking device.
Despite owning the 620, I am not attached to Garmin products. Garmin Connect is crap and the watch, itself, leaves a bit to be desired (good on the run but loading workouts etc can be an ordeal.
That said, the Vivofit does seem to do what I want but keen to hear experiences with such devices.
Or should I just wait for the Apple iWatch and replace the 620 with it?
