The card is recognized without any problem, both in the device as well as the Mac (see below).
The performance figures are totally ok, and as of the other users specified here. Since I prefer to spare myself the renewed items of data.
The only problem with this "Set" is the adapter.
Because the supplied adapter does not work. As soon as I took another, the card is recognized also on Mac and I was able to check the card for errors and speed.
Clear the card can then be send back, but I found the unnecessary since I have them lying around enough.
Other the other hand, are dependent on them, are resent.
