The Evoluent4 Left Wired vertical mouse is a patented ergonomic mouse designed to promote healthy, comfortable, and productive computer use. It features six programmable buttons for customization and a directly reachable DPI-button allowing adjustment of pointer speed across four settings (800-1300-1800-2600). The illuminated Evoluent logo indicates the mouse's status, turning off during system power-saving modes to conserve laptop battery. A built-in lip supports the little finger, aiding in maintaining an upright, neutral hand posture that prevents forearm twisting. This wired mouse ensures ergonomic comfort for all users, regardless of their fixed workplace. The automatic sleep mode, indicated by the logo's illumination turning off, is a thoughtful feature for extending laptop battery life. Constructed from high-quality materials, the dark grey mouse with silver buttons offers a comfortable grip. Connects via USB-A and is compatible with both PC and Mac. Cable length is 2100mm.
