Yeah it's not just eBay - I bought one of these via Groupon http://www.emyub.com/index.php/32-gb-usb-pen.html which turned out the be fake, initially they sent a second which was also fake too finally refunded me when I called them on selling fakes Reported this to Groupon but they weren't interested (they have also sold them via the other voucher sites)
Great program and it does work. It just takes a while if it has a lot of GB's
At uni I have had a few lectures on memory, storing images and data etc, I have, (in the past) bought memory cards to fit various mobile phones which later on decided to corrupt and become unusable, I would never buy from Ebay, or any online place unless it is certified, yes even decent honest retailers can become sucked in to buying cheaper items to sell on to increase their profit margins. If i bought from a shop, Jessops and the like, should the item fail I can simply walk back in to said shop and get a refund or exchange, its a little harder to do this online and I'd prefer to speak to a human. Decent data storage in this day and age is almost essential, given that more and more people store their images and videos on HDD's or memory cards of various sizes. I have to use decent ones given what I do (a photographer) if it corrupts and all my images are lost then the client will not be happy nor will they care how or why it happened. But for those who suspect anything I would recommend backing up images to CD/DVD and an external HDD also to be sure and not just storing on your laptop/pc Just my 2p worth.
Some people like to play the Flash fruit machine. It pays out every time with lemons on every reel.
I've bought reliable flash media from eBay. The secret is generally not to go near it if the price is too good to be true, and that's a failure of judgment that consumers have made for centuries. That said, when a listing for a 64gb microSD card/USB drive actually says "the size could be anything from 128mb to 64gb", you have to wonder just how stupid some people are. Incidentally, faked flash memory is still perfectly usable with a little tinkering. I have a 2gb card (sold as 32gb), which I chased up with the seller and for which I received a refund (and there was no point them paying the return postage). I've been using it without issue in my tablet for more than a year now.
