The WI610 notebook mouse from Fuji meets all my expectations: It frees me always take care of the obligation, if the NB should be provided with angekabelter mouse to another location. Often then the corded mouse fell off or dangling annoying at NB. An operator at a distance not been possible sometimes there was crimping or I was "tied". Now I no longer have all of these problems! Moreover has the mouse over 5 keys, so I thus "page up / down" can use when reading; other key macros can be customized with the included software realize. The scroll wheel can "scroll forwards / backwards" and "click", but by tilting and "left / right". Even the sensitivity can be switched: 1000, 1500., 2000 The receiver protrudes only 5mm from the USB port. Weight with battery: 85g, fits comfortably in your hand and can be guided accurately. Delivered in a small box: wireless mouse, USB receiver, battery, short instructions and CD. Highly recommended!
