@Yveaux I discovered differences, because my circuit was not acting the same always (the problem was a tps2115 power mux), then i compared different orders and its clearly visible that they differ..
I just opened a fake one and it actually looks like an genuie one, except some details and missing revision number on the pcb:
IMHO they did a great job faking this, it looks nearly the same and also works quite similar..
One of the sellers i buyed this was also "Greatwall Electronics", but they accepted the dispute whitout any comment..
