I bought this mouse for work as my old Logitech what trying to give up. The new one is just as precise, but works on more surfaces. More over, the light is now greenwhich makes it more user friendly When its dark and you pick it up (my old one used to try to blind me everytime I picked it up). In contrast with the other users, I am happier with the scroll button Actually - for me it is easy to use IT as a third button, and the scrolling is even better than with the old one.
