I am a professional photoghapher.I have purchased 4 SanDisk Extreme Pro cards with one fire wire 800 card reader from the SanDisk authorised distributor M/s.Tirupati Enterprises Lamington Road Mumbai,India in the month of October2009.I am using these cards in Convergent design’s Nanoflash Video recorder.The cards are working fine but after one month the card reader started giving some trouble while transferring the files. Often my Macbook Pro would not recognize the cards placed in the reader. I noticed that the wires inside the reader are not strait. I personally handed over the reader to Mr.Inder Jain the propriter of Tirupati Enterprise in the month of December2009. I wanted a replacement for the reader. After a lapse two months there is no response. I am an ardent SanDisk fan but after this kind of poor after sale services I am really in pain.
