Key specs explained for this keyboard
Form Factor: Full-Size (108-Key)
This layout includes a complete number pad and function row. You get every standard key for typing and gaming without compacting the design. The extra space suits users who rely on the numpad for data entry or specific game commands. If you prefer a tighter desk footprint, you might look at tenkeyless options instead.
Switch Type: Red linear
Red switches move straight down without a tactile bump or audible click. This results in a smooth, quiet keystroke that is gentle on the ears in shared spaces. The linear action allows for rapid key presses, which benefits gamers who need fast response times. You will notice less finger fatigue during long sessions compared to clicky switches.
Hot-Swap Support: Hot-Swappable
The sockets allow you to remove and install switches without soldering tools. You can easily change the feel of the keyboard by swapping in different switch types. This feature extends the life of the board and lets you customize the typing experience. It is ideal for hobbyists who want to experiment with different switch profiles over time.

This helps relax your wrists during long work or play periods. The finish comes in the Gemini Eclipse colorway, though other options like Cerulean Polar and Black Tangerine are available.
