I bought two of the CycloDS Black and one of them is not quite good. Overall it seems to need a little more force when I'm putting it into the DS. And the microSD need ALOT more force to insert and remove. It seems to work fine but I could swear it's a bit slower than the good one. I don't really know how to measure it. I'm just wondering how I should go about exchanging it? Should I go through CycloDS or Mod Central (where I bought it).
