Did the band now have 2 weeks use. It trÃ'gt pleasantly and looks good. The battery has naturgemÃ'ß held only one day at the first time, the second battery held two days. Now try all functions, and all settings are made has already held 4 days of battery. A big drawback is the display, which gets scratched very quickly. The best will be immediately protectors to buy with. Operation is simple and the connection to my Sony Xperia works zuverlÃ'ssig. I use the band as a sleep control, alarm clock and let me show incoming messages and calls. This all works very well. I use it as a speakerphone for the reason, not because it so entlÃ'd the battery very quickly, but the SprachqualitÃ't is calling for sufficient. In contrast, the works SchrittzÃ'hlung unzuverlÃ'ssig. If I am a craftsman throughout the day in motion come together values 16000-20000 steps, which is rather unrealistic. The band probably zÃ'hlt every move as a step. Amazed me relatively precise detection of the driving and sleeping time. All together it's me 5 star value because I can erfÃ'llt my AnsprÃ'che and waive SchrittzÃ'hlung.
