A4tech Bloody B820R mechanical RGB gaming keyboard

THE WORLD'S FIRST KEYBOARD WITH LIGHTNING-FAST MECHANICAL SWITCHES

Innovative LK Optic Switch technology uses optical switches to ensure lightning-fast response with an extreme 0.2ms keystroke response time. This allows gamers to always be one step ahead of their opponents and enjoy an even better gaming experience

The shortest response time of 0.2 ms!

The innovative LK Optic Switch technology uses optical switches to guarantee lightning-fast response with an extreme 0.2ms keystroke response time. Exclusive "long-lasting" typing sound and tactile feedback deliver an even better experience for gamers.

25% faster keystrokes

LK Optic Switch technology features a key travel of 3mm, which is 25% less than traditional metal switches. (The key travel of traditional metal switches is 4mm.)

Lightning-fast response without any lag

LK Optic Switch technology ensures lightning-fast response with virtually no delay. (Traditional metal switches have a delay of 18-30 ms due to key bounce.)

Exclusive "long-lasting" typing sound

LK Sound Creator technology was developed to provide "long-lasting" sound when typing. Conventional switches create sound when typing using metal friction, and this sound tends to fade after a few months.

Exceptional durability, 100 million strokes lifetime

LK Optic Switch technology guarantees a long switch life of over 100 million strokes. (Traditional metal switches are prone to oxidation and wear out easily.)

Customizable RGB animation

You can freely customize 3 types of RGB animation modes using 16.8 million colors to create your own unique RGB animation.

6 preset RGB lighting effects

The keyboard offers 6 types of preset lighting effects as standard. The lighting effects can be changed without the controller by pressing the "FN" and "F12" keys.

Aluminum alloy panel in Gunmetal finish

The aluminium alloy top panel offers a high-end modern finish and features greater strength and corrosion resistance than a conventional panel.

Anti-Ghost Game Mode

The innovative "Full Anti-Ghost" technology offers N-Key Rollover function, allowing you to press multiple keys simultaneously while playing any game without any functionality limitation or error. By pressing Fn+F8, the "Windows" key can be disabled to avoid any interference.

Spill resistant nano layer

An exclusive nano layer on the circuit board protects this board from corrosion caused by moist air or corrosive chemicals. The result is longer life for your keyboard.

Intelligent water drainage system

Both drain channels and holes are positioned in precise locations to ensure efficient water drainage.

ERGONOMIC DESIGN WITH HIGH DURABILITY

Bloody keyboards feature unique design, precision and quality craftsmanship and state-of-the-art technology. Their attention to detail, comfort and ergonomics make them one of the very best. As one of the most important parts of your gaming environment, the Bloody keyboard is designed to put complete control at your fingertips.
