I have hand my band for a while and I have to say so far I like it. It could be a bit more comfortable to wear and it is a little difficult to use. I wish there was a way to have the step counter calculation which also calculates distant, to be able to perform a self-tune. In other words, when you turn on GPS for a run, it is very accurate on distance. The step counter seems about 10-15% short. So 4.5 miles is only 4 miles when using step counting with out GPS. You would think it is a no brainer to just say calibrate and then the step counter would be more accurate. I cant really tell how accurate the heart monitor is but it seems ok at this point. I will try the step counter on a treadmill and see how the treadmill distance compares with the band calculation.
Well after 2 months of use (using GPS on some runs) the step counter has recalibrated. It was off by 20-25% on the treadmill but now is right on the number. I guess they needed a long sample time before they self calibrated. Would be nice to know more of the internal software in these bands. I want to buy another one but they are still sold out. I was very skeptical and did not think it was a useful device. Now I wear it all the time and think it really helps me keep my fitness on track. (even sleeping) It would be nice to know there plans for the future. A mp3/wma player with a headphone jack or Bluetooth headphone support would be the frosting on the cake.
