Advantages

True PBT double-shot keycaps ensure legends do not fade and provide long-lasting surface durability. Hot-swappable Kailh sockets allow fast, solder-free switch changes. The multi-layer padding and EVA foam layer improve acoustics and reduce noise. Dual-layer PCB offers reliable signal handling and supports N-key rollover. The detachable USB Type-C cable with 1000 Hz polling rate delivers low-latency input for gaming and fast typing.

How to use

Connect the keyboard to your computer using the detachable USB Type-C cable.

Adjust lighting, brightness, and effects using the keyboard’s built-in controls. Set the keyboard angle by unfolding the two-step feet to the desired position. For optimal acoustics, ensure the keyboard is placed on a stable, flat surface to allow the multi-layer padding and EVA foam to perform effectively.

Recommendations

Use PBT-safe keycap cleaners and avoid harsh chemicals; to maintain sound and stability, place the keyboard on a solid desk surface and periodically check that the two-step feet and detachable cable are securely attached. When swapping switches, power off the host device or disconnect the cable to prevent unintended inputs.
