I am not sure about that one in particular. I have the Interact 16X card and it has been working good for me for awhile. I say 'has' because now it has begun to go on the fritz. It is heating up and not being recognized by the GC. I know it is not the GC because I have a nintendo Memory card and it works fine in both slots.
My advice to you is too stay away from 3rd party anything, I have learnt my leason.
Now when is nintendo going to come out with the SD card...
