Disappointing durability

I had an extra something spent more money and scoured the compatibility list before.
The map was compatible with my touch. 3
After 8 months without problems suddenly Anwendeungen stürtzten from who wanted to install data on the SD card.
You could delete data (it was shown that they were gone) and once after power off, for example, rebooting the phone, they were back.
On the map copied "new" data were useless and disappeared after a reboot.
Formatting is not possible regardless of whether on the phone or on the computer.

10 year guarantee are indeed great but then you have to weigh whether one leaves the card with his personal data, which we now can not delete, when returning someone stranger.
With the guarantee have to pay the shipping to the manufacturer himself.
I hope they go with the data to carefully and be destroyed.

Amazon was again exemplary, the refund was caused obwhl the card has not arrived yet, the return label, there were free.

The next one will probably be no more Sandisk.
