I have the dock for my Samsung Galaxy S4 (GT I9500) bought to my phone and my 2nd Battery to load simultaneously, which works great: perfectly invites the station both batteries in the time in which I have formerly my phone battery is fully charged, but I have thanks to the dock now 2 batteries that are full! In addition, the station is very classy and has blue / red LEDs. The surface changes from clear to black matt varnish. It has already been noted from other customers that the smartphone (above) is not particularly easy on the micro USB can attach, which I can agree. However, with some practice and getting used to get so rightly very very good! In addition, it is an exaggeration to say that are damaged by the severe at the beginning or smart phone docking cradle. Of course, I'm assuming that one makes careful that, and not deal with it as if it were a 50cent gum machine toys;) I have now for several days and can only good things to say - just buy it!
