Good quality, good service.

Have this card in a Raspberry Pi in use. Much faster than I had in operation previously.
I have the read / write rate is not measured, but an appreciable difference to the old Class 6 card is present.
(Should also so be ;-)
Unlike some other adapter cards that are in my possession, makes the attached a very stable impression.
No wobbly plastic as with cheap offers sometimes the case.
Through a postman who could not find our mailbox for the first time the program was again sent back.
But thanks to the nice customer service without further problems sent again. All very quickly and easily.
