Indeed, very practical. No need for a mouse pad. Good ergonomic design for both large and small hands. I have already used another mouse trackball for 4 years and when it broke, I had a wired mouse, only 2 buttons and no scroll wheel. Not cool at all when it was used with a trackball. There is nothing better. Forced to regalérer with a normal mouse that is a terrible hassle because you have an internal ball that is without proper shutdown and a very smooth surface. With a trackball not need all that. For me, the trackball mouse is the best mouse.
