Zola1, I'm so glad you asked this. The topic was brought up a while ago and still left me confused. I've also read MANY reviews. I'm looking at the Polar 300 vs the Garmin vivofit 2. I think the reviews are helpful when the reviewer mentions the workouts they do! I'm not a fan of the Fitbit as I've heard too often that it's not tracking the steps correctly, the calories burned is way underestimated etc. Still, it would be nice to have Cathletes chime in as we all seem to do advanced level wkouts. I currently have a Polar FT4. No syncing, tracking, uploading etc. I just don't want to waste time or money and would like something decent. Please share when you make your purchase.
