Traditional mice force you to take one hand away from the keyboard to use them and cause shoulder tension by putting you in an awkward position. For a radical and very successful rethinking of the mouse, look to the RollerMouse PRO. It cleverly builds a pointer control, scroll wheel, and five buttons into a Lycra-covered, gel-filled wrist rest that sits below your keyboard—a solution that's both comfortable and efficient. The RollerMouse PRO lets you keep your hand in place, for better productivity and a more relaxed posture. Its best feature is the roller bar, which sits just above the buttons and lets you precisely control your cursor with only slight finger movements. Download the driver to customize the five buttons.
