Description This premium membrane keyboard features the same keycap design as a mechanical keyboard for a comfortable typing feel. This wireless keyboard with trackball features an optical trackball, right/left click, back/forward buttons, and a mouse wheel, allowing you to simultaneously use a mouse. The EXTRA TOUCH series features a "Step Sculpture" design, where each step is arranged in a staircase-like pattern and the top of each key is curved to accommodate finger movement, and a "Cylindrical" design, where the top of each key is recessed, eliminating mistyping and unnecessary finger movement for a comfortable typing experience. The keyboard features durable keys that can withstand up to 10 million keystrokes. It is equipped with an adjustable tilt stand with two tilt settings. The 19mm key pitch and 108-key Japanese keyboard layout ensure comfortable typing. The receiver can be stored inside the keyboard. A battery level indicator light notifies you when it's time to replace the batteries. It also features a power switch to prevent battery drain when not in use. A gaming-grade, high-performance optical sensor is used to detect trackball movement. The trackball color and coating thickness were thoroughly analyzed to ensure the ultimate in pointer tracking performance. The support ball is made of a large, 2.5mm artificial ruby. By using high-quality support balls carefully selected for their smooth surfaces, the feel of the ball is dramatically improved. The larger diameter of the support ball also makes it less likely to become buried in dirt and fingerprints, reducing the frequency of maintenance. Once you configure the driver utility, the keyboard remembers your settings, allowing you to use the keyboard on other computers without the utility installed. The key bearings are equipped with wear-resistant POM (polyacetal) rings, providing a smooth typing feel with minimal rattle. A soft, cushioned wrist rest is located at the front of the keyboard, supporting your wrists and palms. This reduces wrist strain during extended computer work.
