Perhaps $4 for a 16GB Kingston Class 10 ExtremeX microSD card was too good to be true. That certainly seems to be the case because these are almost certainly NOT genuine Kingston cards and they top out at 4MB/S write speed which is *far* below the claimed performance for the real thing. So, will TinyDeal put things right and send me four *genuine* Kingston class 10 cards or will they simply say "tough luck"?
