Does not work.  I have a card purchased at Best Buy that looks identical side by side.  BUT!  Transferring music onto the Best Buy purchased card was extremely fast.  100+ meg albums transferred in 2 to 3 seconds.  On these cards, a 61 meg album was at 18 minutes remaining with less than a quarter of the album transferred.  I bought two, so I figured maybe a bad card.  Tried the other, same thing.  Extremely slow.  Wonder if they are even real.
