For those who are interested in the 64 GB variant: This fails, as many have already written to me that after some time the write service. This means it can be re-describe neither files nor delete. At my first card, it took two days for my second card after the first record on. The defect always occurred after playing of the half of the volume of data. The positive reviews for this card close seemingly all UK Varaianten with a give and so may give a false impression about the 64GB version from.
