【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. 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 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.
