[An ergonomically shaped trackball that reduces strain on the wrist and elbow. Thumb-operated type. Wireless.]
●This wireless trackball has an ergonomic shape and an ergonomic design that reduces strain on the wrist. ●The new design allows you to lightly support it with your hand from the side rather than resting your hand on top, reducing twisting of the wrist. ●It can be held at a natural angle, so it does not strain the wrist even when used for a long time. ●It is a trackball that controls the cursor by rolling the ball with your finger. ●It uses a medium-sized 34mm ball that is just right for moving with the thumb. ●The cursor speed can be switched in four stages: 400, 800, 1200, and 1600 counts. ●Silent switches are used for the left and right buttons and the side button. ●It uses the 2.4GHz digital band which is resistant to radio interference, and stable data communication is possible over a wide range of up to a radius of 10m. *Only when there is no radio interference. ●Equipped with a power ON/OFF switch to prevent battery drain when not in use. ●The receiver can be easily stored by simply plugging it into the back of the mouse body.
