This "red" Mau is, really, white pink! And I think it's great. It is a super petite mouse for woman hands, not too small, not too big. An AA battery is already included. Then just the Mini USB plug into the computer and you work all by itself. This USB connector can be stowed under the mouse in a small compartment, if you pull it back. An u. Off not forget. Full class part for narrow :-)
