I have purchased two SanDisk Ultra SDHC - I class 6 - 8 GB at the photo fair -2012 here in mumbai, india. The product serial number on these cards is No. SDSDH-008G-U46.
However, i find no listing of this product on sandisk.com or on any other sellers page. It makes a bit suspicious if I have got fake cards on my hands. I may be totally wrong.
Any guidence would be greatly appreciated.
