An epic core inside
A powerful ARM architecture MCU equipped with 256KB Flash provides greater flexibility. The polling rate is 1000Hz on 2.4GHz and in wired mode right out of the box, which makes latency almost imperceptible even in competitive games.

Low-profile double-shot PBT keycaps
The K3 Max is equipped with unique double-shot PBT keycaps made from a durable, non-shine-through material that is impervious to light and has excellent oil resistance for long-term use.
Redesigned stabilisers
Redesigned stabilisers remain at the same level as the switches, ensuring greater reliability and less wobble on large keys like the space bar, left shift, backspace and enter.
Ergonomic support
Three levels of angle adjustment for typing aim to provide long-term ergonomic support for your wrist.
