A4Tech B830 Bloody LK Mechanical Gaming Keyboard

Innovative LK Optic Switch technology uses optic switches to react at lightning speed with extreme 0.2ms key response, exclusive "long-lasting" typing sound, and tactile feedback, creating more passion for gamers.

LK Sound Creator Technology was developed for “long-lasting” typing sound, while a regular switch uses metal friction to generate typing sound and tends to fade away after several months.

LK Optic switch has a life span of over 100 million keystrokes. (Traditional metal switch tends to oxidize and wear out easily)

LK Optic Switch travel with a distance of 3mm, which is 25% faster than traditional metal switches. (Traditional metal switch travel at a distance of 4mm)

LK Optic Switch reacts at lightning speed without lag. (Traditional Metal Switch delays 18~30ms due to metal bouncing)

The top panel is made of aluminum alloy for a cutting-edge tech finish and provides stronger and more resistance to corrosion than the common panel.

Dazzling backlit makes you stand out in the dark.

Engineering for human ergonomics ensures maximum comfort.

Full NKRO ensures each keypress can simultaneously register regardless of how many keys are being pressed or held down at a time including modifier keys (Shift, Control, and ALT).

Space-Bar is made of dual screws + dual springs + a balancing bar for best durability.

The 8 gaming keycaps are designed for longer comfort usage.

Exclusive advanced Nano-coating over the PCB board protects the PCB from corroding by wet air or caustic chemicals, prolonging your keyboard lifetime.
