This inductive charger is a practical matter: replace the back in a minute and from that moment you need to put the smartphone is on the cradle, according to the manufacturer, there is a overload protection. I am pleased that the fiddly plugging the charger eliminates normal, just in the evening (or as needed) place it on the charging station and already you get his phone recharged elegant. Since I do not use cover, there were no problems, because the unit is 1mm thick. The word 'Zen' (instead of the original 'Samsung') I would not have noticed if it had not been criticized here several times, I can live with it.
