Did the shell in use daily. In the beginning everything was great. Laden went smoothly, enabling the battery as well as to charge the iPhone. Later, the battery and the iPhone could only be charged in a certain position of the charging cable, as apparently move the contacts in the envelope to the back and there is no contact to the charging cable. Now it invites no longer correct, the lights flash on funny (sometimes just one, sometimes 3, times 2 ...). And even with a lot of effort and luck I manage the charging cable to bend so that it boots überhuapt.
Return shipping is applied at Amazon. Too bad that this occurs after just 6 months. Otherwise, the shell was really great! Perfect fit and stable.
