Maybe I'm still a bit paranoid about the fake Sandisk cards on eBay but I just received a M3 Perfect MiniSD from http://www.gamersection.ca and the card looks nothing like the M3 cards I have seen in all of the reviews? Instead of the usual white plastic casing as seen on the official M3 site and in reviews such as this one... http://www.iso420.com/nds/m3sdm/index.htm my M3 Perfect MiniSD is in some type of see through plastic casing that does not seem very well built. The edges of the card do not even fit together perfectly. There is a seam down one side. I haven't tried it yet because I'm still waiting for my MiniSD card to arrive. Has anyone here ordered from the Gamersection site before? Is there such a thing as "fake" M3 cards?
