Additionally, it can be used to adjust settings such as volume or RGB lighting effects, providing a tactile and intuitive way to customize your experience without needing to use software.

Tell me about the RGB lighting options available.

The CK108 boasts vibrant 16-million color RGB backlighting with 22 different lighting effects. You can customize colors, change the speed of effects, and select different modes to create an impressive and personalized lighting setup that enhances your gaming or typing environment.

Is the keyboard suitable for gaming?

Yes, the CK108 is designed with gamers in mind. Its ultra-stable magnetic switches minimize key wobble and provide precise actuation with adjustable stroke lengths, ensuring fast and accurate key presses. The reliable wireless 2.4GHz connection and customizable RGB lighting further enhance the gaming experience.

What is the operating force of the magnetic switches?

The magnetic switches operate at an average force of 45±10gf, with a minimum force requirement of 35gf. This balance ensures the keys are neither too stiff nor too light, providing a satisfying tactile feedback suitable for both typing and gaming.

How large and heavy is the keyboard?

The CK108 measures 43 cm in length, 12.5 cm in width, and 3 cm in height, weighing approximately 1.5 kg. Its full-size 108-key layout offers a familiar typing experience while maintaining a solid and durable build.

Do I need to calibrate the keyboard after swapping switches?

Yes, after swapping out switches, especially when changing between different types or brands, it’s recommended to calibrate the keyboard. This ensures that the keystrokes are registered accurately and the adjustable stroke settings function properly.

Can I use the keyboard with multiple devices?

Typing Experience

The CK108 HE’s magnetic switches are designed for stability and minimal key wobble, which can improve accuracy and consistency. Adjustable actuation points let users set the exact key travel distance, which may benefit those who want a shorter or longer stroke than typical mechanical switches. The keyboard supports both magnetic and traditional mechanical switches, giving users freedom to experiment with different switch types.

Connectivity

This keyboard supports three connection modes: wired via USB-C, wireless 2.4GHz with a receiver, and Bluetooth.
