The product is well designed, I got the black one and it's beautiful, looks well, the led is impressive, and it fits well. The fact that it has 2 links for extending is nice. The plugging into usb port is fine.
My complain: Calories tracking is completely inaccurate. I hopped on the treadmill and the number was off by 20%. I hopped on the elliptical and the number was off by a lot (15 minutes, treadmill was 180 calories and band was 30). The fuel system gets some time to get used to it. If you want this as a calories tracker, it will just not work.
