This charger is very simple and exercised its functions charger and data transfer USB 3.0 micro (connected to a PC). Delivery a bit longer than usual but at this price it is very forgiving. Only small problem compared to my samsung station S3 / S4, it does not display the calendar and desktop clock but remains in the home screen. A little more, my Galaxy S5 has a slim notebook case which is no problem to get into the housing in the open position and without forcing. Finally a quality / price ratio.
