This card & adaptor does not come in a manufacturers security blister pack.  It is packaged only in a standard opaque plastic SD case which is sealed with a blank paper sticker. 



I was concerned when I first saw the packaging, having read plenty of warnings about fake cards that report incorrect capacities and become corrupted after a short period of use.  I was right to be concerned, though I didn't realise it immediately. 



Having scarcely used the card since purchase, I recently came to give it a proper trial and was confronted with a message from Windows 7 saying "media needs to be formatted before use"... Err, sorry but no it doesn't; I already did that weeks ago!  Ok, so I play along... "Windows cannot complete format"!  Several attempts later the card finally formats & shows up as an available device but by this time I'm reading hundreds of dreadful reviews from people who bought the same card (in non-security packaging)... and am now afraid to store anything important on it in case it becomes corrupted! 



The card is no good to me if I can't trust it.  Might as well just delete all my files outright & cut out the middle man so to speak! 



Also of note, I tried it in my phone, A Samsung Galaxy Y smartphone (running Gingerbread)... The phone didn't even know it had been inserted!  Says it all in my opinion. 



Apparently you really do get what you pay for.  In this case, bad mojo! 



One star for the fact that the card is sold with an SD adaptor card... now THAT I can use!  Otherwise no stars at all!
