Kullanım Talimatları
1. Ergonomik Tasarım ve Kullanım
The vertical ergonomic shape and thumb-controlled trackball are designed to reduce forearm rotation and wrist strain, promoting a more natural hand posture during extended use. Cursor movement is achieved by rolling the trackball with your thumb, eliminating the need to move the entire mouse.
