Features

• This premium membrane keyboard adopts the same key top design as the mechanical keyboard and achieves a comfortable typing feel.
• This wireless keyboard with a trackball features an optical trackball, mouse right/left click, back/forward buttons, and mouse wheel functions, and allows simultaneous mouse operation.
• This is the EXTRA TOUCH series that achieves comfortable typing by eliminating erroneous input and unnecessary finger movement with the "step sculpture structure" where each step is arranged in a staircase shape and the top of each key is curved to match the movement of the finger, and the "cylindrical structure" where the top of each key is depressed.
• The keyboard features durable keys that can withstand up to 10 million keystrokes.
• Equipped with a tilt angle adjusting stand that can adjust the tilt angle in two steps.
• Uses 19 mm key pitch for easy typing and Japanese 108 key array for comfortable typing.
• The receiver can be stored inside the body.
• It is equipped with a battery level indicator that tells you when to replace the battery.
• Equipped with a power switch that prevents the battery from running out when not in use.
• A gaming-grade high-performance optical sensor is used to detect the movement of the trackball. The optimal color of the trackball and the thickness of the coating layer for the optical sensor are thoroughly analyzed to achieve the ultimate in pointer followability.
• Large artificial ruby with a diameter of 2.5 mm is adopted for the support ball. By using the highest quality support balls that are carefully selected only for those with smooth surfaces, the feeling of ball handling is greatly improved.
• In addition, by increasing the diameter of the support ball, the support ball is less likely to be buried in rubbish such as hand rubbish and the maintenance frequency is reduced.
• When you make settings in the driver utility, the keyboard remembers them, and you can use the keyboard with the same settings on other computers without the utility installed.
• Wear resistant POM (polyacetal) ring is mounted on the bearing of the key to achieve smooth keystroke feeling with little rattling.
• A soft cushioned wrist rest that supports the entire palm from the wrist is placed in front of the main body. Reduces the burden on the wrist caused by long hours of computer work.
