Shine the first I have received as new was, unfortunately needed because the bracelet was already paired with a phone. Unfortunately it is not possible to cancel the pairing again if you do not own the corresponding Apple or Android device. After endless research on the Internet I was able to learn the same, that there is no community to which busy and the manufacturer side does not help. OK, have not sold the debt of the bracelet but Amazon that used for new. But In defense I must say that the replacement was initiated immediately with my complaint in a known manner. Now for the bracelet. I did the first time in conjunction with an iPhone saw and was impressed by its features. Since I have always wanted a new, light and waterproof clock, me this clock was just right with Fitnesfunktion. But then came the disappointment, because I have an Android device that supports one of the few new, currently available Androidphones ever Bluetooth Near Field Communication. Coupling went smoothly and the few settings were done quickly. And now comes one of the crucial points for this bad review: The Android app is unlike the iPhone App a bad joke. For this is important to know that you always have to look at the bracelet in conjunction with the corresponding app as a product, since no part makes sense on its own. Apart from the home of the app is in Android Nil. No statistics, no graphical display, no different modes, nothing. If the manufacturer as not very strong nachbessert, no one is sure about with happy. The bracelet itself is nice and light and really waterproof if you have done it once to get it out of the package. I thought I'll break me out while keeping our fingers crossed. Functioning did the part quite well, if you are not too much to let it rumklopft eg as occasionally show the time with me. The Klopferei is hit or miss and it is in favor of Shine whether it can illuminate its LED's. The three-time tapping to switch to sleep mode, one can ever lose sleep. To summarize: In conjunction with Android this combination is in Beta stage maximum. The hardware alone is there but still not quite out. Meanwhile, the money is in my account again and I'm wearing another nerve soothing analog clock.
