ELECOM Wireless Mouse Large 8 Tilt Black (Receiver Included), Trackball, Ball, Buttons, Function, M-HT1DRXBK

The "HUGE" is a wireless trackball mouse designed for index and middle finger operation, featuring a large 52mm diameter ball that allows for wider pointer movement with a single touch. The top surface of the device features a palm rest made of low-rebound material that can accommodate the entire hand, from the wrist to the palm, reducing strain on the wrists during long hours of PC work. The trackball's movement is detected by a high-performance, gaming-grade optical sensor. By thoroughly analyzing the optimal trackball color and coating thickness for optical sensors, and completely redesigning the trackball from the ground up, we have achieved ultimate pointer tracking performance. By using top-quality support balls made from large 2.5mm diameter artificial rubies, carefully selected for their smooth surfaces, the feel of controlling the ball has been dramatically improved. In addition, the larger size of the support balls makes them less likely to become clogged with dirt and grime, thus reducing the frequency of maintenance.
