Product that perfectly matches what I was looking for work, at a more than fair price. The metal case is solid and compact, easily I concealed under my office to share a printer / scanner / fax between two pc (one with XP, the other Windows 7). It works perfectly with Windows 7. The changeover is done automatically or by pressing CTRL + F11 or the icon of the taskbar (you obviously installing the driver software on mini CD), or manually by pressing the buttons of the case. Ordered Friday, delivered on Monday.
