I am an analyst and I only use Logitech trackballs. Decided to try this one. Almost impossible to scroll comfortably. I have very small hands and still find it awkward. To doubleclick you have to use one of the side buttons because there isn't a scrolling wheel. I am sure it would work fine for someone who is an occasional computer user. But if you are working long hours with Access and Excel don't even think about this mouse. Have gone back to my wireless Logitech 7-button mouse. Just wanted a trackball that was corded.
