The eBay ones are fake. If you buy one, you will simply be wasting time and money- if eBay refuses to cover your loss.
Someone posted that they got one and it worked, but I do not believe them. There is no such thing (yet) as 32gb microsd clones from China, since the fab process is CRAZY complex and expensive, hence the still short supply, $200 microsd class 2 cards.
32gb is a prodution wall for this tech. It will be a loooong time before they are 16gb level price and forget about class 4 or higher, anytime soon.
That said about not believing a poster on another thread about this, it would be shrewd of a thief to sell one good card to bait others. The seller (thief) would then bank on making up the loss and rake in the cash before eBay shut them down.
One 32gb card for $180 loss and then $15 profit for each 2gb card sold as a 32gb. If I were a thief, I would like those odds.
