Adesso iMouse T30 Wireless Programmable Trackball Mouse

Keep pointer control in one fixed location with a palm-grip trackball that is operated by the thumb. The Adesso iMouse T30 supports right-handed use and pairs an internal optical sensor with five selectable sensitivity levels from 400 to 4,800 DPI. This control method reduces the desk travel required by a conventional mouse and suits workspaces where available mousing area is limited. A 2.4 GHz RF wireless connection links the mouse to a computer through its USB-A nano receiver, with an operating range of up to 30 feet. The receiver stores inside the mouse when it is not connected. Seven buttons, including forward and back controls, can be customized through the programmable driver; the driver also supports profiles and macros. A scroll wheel supplies conventional document and web-page navigation alongside trackball control. The 1.25 inch trackball can be pushed out from the rear of the housing for direct cleaning, then reinstalled without disassembling the mouse. The black housing measures 6 x 4.3 x 2 inches and runs on two AAA batteries. Its combination of a removable thumb trackball, programmable controls, wireless USB-A connectivity, and adjustable optical sensitivity distinguishes it from basic fixed-sensitivity wireless mice.
