I have the tape now about 4 weeks, always on your wrist and you hardly notice it. What was a bit "awkward", is registering with Xiaomi, but even that gets you down. Must indeed be only once. The LEDs are very net but not really helpful because I have usually a shirt or jacket over it so I can see the parts actually never blink or light up. The band has a Schritzähler or a motion sensor that counts the steps and works brilliantly. Furthermore, the band distinguishes between running and walking. What I liked a lot, which is tracked and the sleep rhythm. It is recorded when it is in the light and deep sleep. As far as I can tell, it works well. The star deduction there are really only for because the tape is not compatible with any cell phone. I had a Wiko Highway, which was no connection to conditions. With my Galaxy S5 duo funktioiniert it properly. All in all, I would buy the tape again, it has besides the mentioned still a lot of other important features for me that I do not want to miss.
