A large artificial ruby with a diameter of 2.5 mm is used as the support ball. A left-hand/thumb-operated wireless trackball that is equipped with reliable basic performance and unprecedented new functions, and achieves advanced pointer tracking. A left-handed, 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 the frequency of maintenance. 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 makes it easy to operate, as if the shape of your palm is mirrored.
