how about writing a ebay guide about it

I bought a fake too, trying to warn others, but ebay only allowed 5 messages per day.

well, my 32 gb micro sd card which arrived today only shows 488 kb after formatting, from a seller who has a 100 % favorable rating.  let's see what he has to say, if he responds.

Same old story... wrote a "guide" about bogus memory sticks when I got burned ages ago...

One learns the hard way there are things you SHOULD NOT BUY on eBay....

Memory sticks/cards - 90% plus are KNOCKOFFS, FAKES, or just plain complete garbage.

Batteries - another prime knockoff target, since "OEM" products are often expensive for "extra" batteries, and they are pretty easy to "copy"

"Gold", "825 Jewelry", pretty much ANY shiny thing that  might otherwise be valuable if REAL...

ANY "name brand" merchandise that is being shipped from China/HK, odds are between 99.9 and 100% it's a knockoff/counterfeit

Yep, I know, I just described a LARGE portion of "inventory" in many eBay categories, but it is what it is.

FWIW, at one point I tried helping eBay clean out the fake Memory Stick sellers - category listings were reduced almost 80% at one point, but within days, the "sellers" (ripoff artists) were right back, selling under new account names...  you can't "fix" the problem unless you truly want to stop it properly... eBay makes too much money off all the sales from these sellers, and ruins it's OWN market reputation in the process! 

Anyone familiar with the knockoff market knows it's pretty hard to stop - customs can only catch the big containers of fakes, and those once in a great while.

As long as eBay is a "channel" to send hundreds of thousands of counterfeit/fake items through the mail, one piece or a few at a time, it will continue.  There's simply a lot of money at stake!

EBay doesn't necessarily "like" this, but they are monetizing it by taking a "cut" on all the sales.  Short of posting a huge warning about the potential of buying fake/counterfeit merchandise and shutting most of the China/HK sellers down altogether, they can't possibly put a "stop" to it.  Tiffany's tried a few years ago with litigation, I don't think that went too far.

Like I mentioned, I worked with eBay to shut down fake sellers in a SINGLE item at one point, with reasonable success, but it didn't take long for "new" China/HK sellers to bubble right up and back to the same mess!  Multiply that by the hundreds of listings for memory and batteries, not to mention all the other items that are typically knocked off... it's like spitting in the ocean!

Best thing is for the buyer to BEWARE, if you DO get fake stuff, be sure to leave accurate and appropriate feedback - enough of those, and the sellers flounder, and MAYBE eBay can do something about them on a case by case basis...

Many of the Chinese sellers have set up "outposts", including ones in the US, so they can ship faster... 

THUS, the second "aware buyer" question set needs to be "is the price 'too good to be true'?", and if it's a name brand product, how or why is a seller acquiring large quantities and selling them "so cheap".  Of course if you ask, they'll have some wacky story "explaining" it, but that also might be a clue...

Unfortuantely I had this issue today, card came out to be 12 kb!! What can I do with THAT?! Nothing...

After sending seller this message:

I bought a memory card from you, but no matter where i put it, it says there is 12 kb available. Now unless you want a case opened against you on Ebay, Paypal AND negative feedback, i suggest you refund me my money

I got full refund IMMEDIATELY.

Got me too... Just because of these situations ebay should allow you to edit feedback. Im waiting on the sellers response to see what type of customer service i get.

I had this same issue! I ordered a generic 32gb micro sd card for use with my Samsung Galaxy Note 2.  I had issues immediately! First I installed it in the phone and transferred all my media to the card.  All the data became corrupt and i ended up loosing at least the last 2-3 weeks of media since my last backup to my pc including the only copies of videos and pics of my 2 month old daughter.  I then could not get the adapter to work on my pc and had to use an older adapter I found laying around.  I formatted the card and transferred my last backed up files to it and it seemed to work fine for 2 days.  I reached about 2.6gb worth of files on the card (i transferred a back up containing pics and other media I've collected from phone to phone over 5yrs) and then I noticed videos and pics no longer working or showing up in the gallery or files list.  I contacted the seller and havn't heard anything back thus far but Im very disappointed and learned my lesson!  LEAVE GENERIC SD CARDS ALONE! I ordered a 32gb Sandisk Ultra class 10 micro sd.  It's better to pay the extra money for quality, performance, and a trustworthy name then to loose priceless moments of my babies life because of a bad sd card!

I can tell you from vast expereince of the Chinese market and especially suppliers in the Shenzhen area that there are significant numbers of counterfeit cards out there certainly in the Sandisk Brand. Let me make it clear that if they are for sale for under £20 on Ebay the chances of them being fake are extremely high because the cost price of the real thing is such that you would lose money selling below £20.

If you are a retailer word of advice is before you buy you need to see all the technical documents for CE certification and these need to be from a recognised test house like Intertek or SGS otherwise your being scammed because if they can counterfeit the card they can certainly counterfeit the paperwork.

I got burnt too with this scam. When transferring info my card started to give trouble between the 4 - 5 gb mark, and I lost quite a bit off data as a result of that.
