## Long description

The A4Tech B820R Gaming USB Black is a full-size (100%) wired gaming keyboard that uses LK optic mechanical switch technology to deliver extremely fast key response and extended durability. The top panel is made of gunmetal aluminium alloy and the keyboard includes full N-key rollover, spill-resistant nano-coating, and a smart water flow system for improved protection and longevity. RGB backlighting offers preloaded effects and a self-customize mode with 16.8 million colors and shareable profiles.
Advantages
LK Optic Switch technology provides a 0.2 ms key response with zero digital latency and a reduced travel distance of 3 mm for 25% faster actuation compared with typical 4 mm metal switches. The switches are rated for over 100 million keystrokes. The keyboard supports full NKRO for simultaneous key presses, preloaded and user-customizable RGB animations with 16.8 million color options, and a corrosion-resistant aluminium top panel. Additional protections include an exclusive nano-coating over the PCB and a precision-engineered water drainage system.
Suitable for
 Competitive and casual PC gaming where low input latency is critical
 Long typing or streaming sessions that require durable keys and ergonomic design
 Users who want customizable RGB lighting and the ability to share presets
 Environments where occasional spills may occur thanks to nano-coating and drainage
