Meet one of the newest models of the Adesso trackball product line, the Adesso iMouse™ T40. It incorporates the claw grip design where each user can rest his entire hand over the mouse. The trackball location allows users to move their cursor by rotating the trackball with their fingertips to reduce the need of hand movement. It is cable-free by utilizing the 2.4 GHz radio frequency technology, offering a wireless range of up to 30 feet. It's also fully programmable, meaning every mouse button can be customized to your preferred function with its programmable driver. With its 5 levels of DPI resolutions (400-4800), the optical trackball provides superior accuracy and smooth motion, reducing hand movement and space. This mouse trackball is also easy to maintain - just push trackball outward from back, clean and push it back in place.
