The Fitbit concept is great, the machine counts accurately, the mobile app (in my case, iPhone) is clear and easy to use. Unfortunately, the FitBit Flex Bracelet has (not the Tracker) a few shortcomings. My wrist circumference is 22 cm, which is already the outermost limit of the men's bracelet. The fact that I can not wear it loose, it scrubs. If you have not thought about the target group of overweight people here? Not all those who buy a sports bracelet, are athletes. In addition, the band at its thickest point is 1 cm thick, thus it contributes fairly to. Good device with poor comfort.
