The Expansion Card is as described, very easy to fit and performs well. It does what it says 'on the tin'. On the positive side it included 2 splitter cables so no problem with power supply as USB 3 needs 900ma. On the negative side the driver cd did not have the drivers for this product and the cd difficult to follow. After installing the wrong drivers I resorted to the web and, although most of the website is in German, I managed to find the correct drivers and now all is well.
