ELECOM Mouse Wireless Trackball Red Ball 6 Buttons Tilt Function and Right Adopts Gaming Grade Optical Sensor Black (Thumb) (Left Scroll) M-XT3DRBK-G

This is an advanced thumb-operated wireless trackball with solid basic performance and unprecedented new features. 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. By focusing on the six skeletons and muscles of the hand that come in contact with the device during operation, and by taking into consideration the depressions and bulges in the design, we have created a new ``comfortable place'' that feels as if the shape of your palm is mirrored, making it easier to operate. Equipped with a speed change switch that allows you to change the pointer movement speed to two levels: 1500/750 counts. Equipped with one customizable function button located on the ring finger.
