Compared to a standard mouse, the ball provides smoother operation, dramatically improving the efficiency of your computer work, especially with dual monitors.

Being wireless also offers excellent portability. Unlike wired mice, you can use your computer from your desk, sofa, or even in the comfort of a futon or kotatsu (Japanese-style table) when it's cold, without needing a mouse pad. [Size Notes] As a vertical trackball mouse, the EM05 Trackball Mouse is best suited for medium and small hands. Please note that larger hands may find the space for their pinky finger narrow and difficult to get used to.
