I was just very impressed. The processing, the protective bag and the cable were good. I once charged my phone (S3) at least 4 so. And then there was already the bitter disappointment. Right the first time charging, it had otherwise only once fully charged upon receipt, it was not working. For hours the LED blinked only to himself, and it seemed obvious no charging place to find. Even the exchange of cable did nothing. Whether on your laptop or wall outlet. Unfortunately very disappointing.
