I recently purchased the fit 2 and it worked fine until it had an update. Then it wasn't counting distance or steps accurately. I sent it back and purchased the gear fit 2. It started off perfect I was getting pretty much the same accuracy with my running group who have different make fitness watches. Then I go and update the watch and the same thing happens. It's way out on accuracy. This is a problem that needs fixing samsung as these trackers are useless at the moment.
