Purchased about 5 years ago. I haven't used it much since I received another keyboard! It's a full-size, wired keyboard designed for gaming. Features: • Membrane (Mech-Dome switch) Rubber dome switches designed to provide a mechanical feel. → Relatively quiet keystrokes, lighter than typical mechanical keyboards. • RGB Lighting Compatible with "LIGHTSYNC RGB," allowing you to choose from approximately 16.8 million colors. → Enables lighting effects tailored to games and custom color zone settings. • Durable and Spill-Resistant Design Designed to withstand a certain amount of splashes and spills. → Provides peace of mind even during extended use or when drinks are nearby. • Media Control Keys Features dedicated keys for one-touch operation of play/pause, volume adjustment, etc. • Integrated Palm Rest The wrist rest is integrated into the main body, reducing fatigue during long hours of use. Specifications: • Connection: USB Wired • Key Switch: Mech-Dome (Membrane) • Key Rollover: Supports up to 26 simultaneous key presses • Size: Full-size (with numeric keypad) • Weight: Approximately 1,000g • Software: Compatible with Logicool G HUB (RGB and key assignment changes possible)
