Experience Tesoro’s Optical Switch Technology
Optimize your game with unparalleled fast movements, zero-lag, and precise actuation via infrared communication.


Optical keys foster durability and longevity
A non-contact signal through optical communication eliminates double typing, delayed response times and defects that come from traditional metal contact. With no oxidation and a particle and spill resistant component, enjoy a longer lifespan.

Anti-particle and spill resistant protection
Liquid resistant coating over the PCB for accident protection for those not-so-lucky moments. The Tesoro Optical Switches are water resistant as they don’t include metal components that may rust.
*The keyboard is splash, water, and dust resistant and was tested under controlled laboratory conditions with a rating of IP56. Splash, water, and dust resistance are not permanent conditions, and resistance might decrease as a result of normal wear. Liquid damage is not covered under warranty.

Total key customization for personalized functionality
Customize your keyboard via Instant Macro Recording, Instant Lighting Recording – both static and dynamic options and unlimited key programming.
Customize up to 4 Tesoro Optical Switches
Some keys may work better with a different switch. If you have a blue switch board, swap up to 4 switches with red switches for a more customized experience and vice versa!


32bit ARM Cortex Processor & 512KB On Board Memory
Experience maximum speed and memory for 100% performance, with zero lag.
Full N-key/6-key rollover options
Ensure no key strike will be missed.


Adjust keyboard angle with built-in kick stand
