The Skyloong GK104 Pro Dual Calculate 2025 Upgrade is a full-size mechanical keyboard designed for users who want a versatile typing tool combined with a built-in calculator and display. It suits professionals and multitaskers who benefit from quick numeric input and on-the-fly calculations without switching devices. Its wireless and wired connectivity options support seamless use across multiple systems.
The keyboard uses linear KTT Rose Silver switches with moderate actuation force, suitable for users who prefer smooth keystrokes without tactile bumps. Hot-swappable sockets enable switch replacement without soldering, allowing customization or maintenance. Three adjustable typing angles provide ergonomic support for extended use.
Supports Windows, macOS, Android, and iOS devices through wired, 2.4GHz wireless, or Bluetooth connections. Bluetooth supports dual device connections, while wired mode offers low latency with an 8000Hz polling rate. Wireless polling rates are lower, which may affect response speed in some scenarios.
