For me, this little object is fine with me! It is discreet (although it is thinner) and calculates very well my steps and duration of my sleep. If you do not have an Xperia, you must download applications GooglePlay 3: smartband, SmartConnect and Lifelog. It's a bit tedious. After that, the software is particularly Lifelog complete: it calculates the number of course not but if they are normal or not a race but also the time that you spent with jeuxvideo, watching a movie, reading a book (if you have installed on your such a reading light)
For those who have a connection bp since the update under lollipop (I have a G3 Lg android 5.0), the solution: - Disable Bluetooth a second 10aine - Reactivate it - If that does not work is that the smartband is paused. To do this, just press the button to reactivate the smartband
Battery side, you have not expect too much ... I hardly reach the 6 days Compared to my old xiaomi Mifit 30 days -_- '
