I got this product after the data cable for my K850i broke, leaving me unable to transfer photos from my phone onto my PC. I have to say that it is a great piece of kit, it allows for quick and easy transfer of files from my phone onto my computer, its even better than the (broken) data cable supplied with my phone used to be. No need for any software- just simply slot you memory card in, drag an drop files onto your PC, fold the card reader up and away you go! it actually allows for swifter transfer of embarrasing drunken photos onto Facebook than ever before. A true pocket rocket!
