I've bought because my PC Playstation Portable did not recognize the Hama card reader. When you consider the price at which this device will be offered, one could easily think that it is good for nothing. But the opposite is the case! This part can actually read all the memory sticks there and that without any adapter. For me it works beautifully and completely without drivers. Simply connect and already went off. I can only say that I am more than just happy, this card reader is just great.
