ELECOM Trackball Index Finger 8 Button Tilt Function Wired Black M-DT1URBK

For more information, please check Product Specifications and Product Description . DEFT is an index finger operated USB trackball that boasts overwhelming operating performance. Equipped with 8 buttons: left and right buttons, forward/backward buttons, a tilt wheel, and three function-assigned buttons. The sensor that detects the movement of the trackball is equipped with a gaming-grade high-performance optical sensor, and a new high-performance lens and optimized peripheral optical design have achieved outstanding pointer tracking. By using a large artificial ruby with a diameter of 2.5 mm as the support ball, the ball handling feeling is improved. In addition, the larger diameter of the support ball makes it less likely to be buried in dirt such as hand marks, reducing maintenance frequency.
