Microsoft mouse to the quality of what I expected. The packaging is well presented, we feel that it is not the Chinese counterfeiting. She needs only one AA battery to operate which is included in the packet (which is more known brand) The wireless dongle running smoothly. The mouse is accurate, seems solid, the pads are wide and so it slides perfectly.
Except on the bed, the edges of the mouse give the impression of "scratching" the cloth which is a bit unpleasant, and there is no DPI change button.
