It features a new design that allows you to lightly rest your hand on the side, reducing wrist twisting. You can grip it at a natural angle without twisting your wrist, so it won't strain your wrist even after long hours of use. When you place your hand on the mouse, your fingers naturally position themselves on the left and right click buttons. Equipped with a high-performance laser engine, it can read the surface of glossy materials that were difficult to identify with conventional optical sensors. It is equipped with side back and forward buttons, allowing for speedy web browser operation. You can easily switch the cursor speed to 800 counts, 1600 counts, 2400 counts, or 3200 counts by simply pressing a button, depending on your needs.
