Until now I do not regret my purchase especially at such a low price (under 14) the shell is not too thick and it holds up well over time by allowing my iPhone 4 to hold easily all day, small flat if we may quote on other shells that I used there were 4 witnesses charge that allowed me to know the battery shell, on this one it is not the case and you not realize the total discharge of the battery you first hand that, in finding the right upper screen smartphone disappearance of the charge symbol (lightning) but basically nothing insurmountable well, ah yes, otherwise the connections on this shell is not the micro USB but pin 30 pins used to load usual iPhone. It can also arrange the some!
