Sun Type 7 mouse

The Sun Type 7 Optical Scroll Mouse comes with 3 buttons with optical tracking and scroll wheel. Optical sensor records motion more precisely than a traditional mouse. Ease-of-use and increased reliability since the optical sensor eliminates moving parts, such as the mouse ball, allowing the mouse to work on more surfaces. Reduced moving parts also means less parts to wear out or collect dust/dirt. Mouse scroll wheel offers convenient, faster scrolling through documents without clicking on scroll bar.
