  The palm rest of the low-repulsion material that the entire palm is placed from the wrist is adopted on the upper surface of the main body, reducing the burden on the wrist due to long PC work.
  The sensor for detecting the movement of trackballs is equipped with a high-performance optical sensor of the gaming grade.
  We have achieved the ultimate pointer-following performance by thoroughly analyzing the color of the trackball and the thickness of the coating layer, which is optimal for optical sensors, and reviewing the design of the trackball from the beginning.
  By adopting a large artificial ruby with a diameter of 2.5 mm for the support ball, and using the highest quality support ball that carefully selects only the smooth surface, the ball feed feeling is greatly improved. In addition, the large support ball makes it difficult for the support ball to be buried in garbage such as hand dust, and the maintenance frequency is reduced.
