GASKET-MOUNTED STRUCTURE: Unlike the traditional screw fixed structure, the positioning plate of the SKY81 creamy keyboard is fixed in the middle by the pressure of the upper and lower shells. There are gaskets distributed around the positioning plate to prevent direct contact between the interior and the shells, acting as a cushioning layer and effectively reducing vibration and noise generated when typing. This keyboard feels soft and even, elastic and has pure sound. 5-LAYER SOUND ABSORBING FILLING: In order to improve the noise situation, this gasket keyboard is equipped with a IXPE foam pad, PORON foam, diaphragm, EVA soundproofing foam and silicone absorbing pad in the gaps between the positioning plate, PCB board and bottom. This reduces the resonance space inside the keyboard, thereby suppressing hollow sounds and making every key press comfortable and pleasant. For gamers and office users, this keyboard is a great addition to the desktop. HOT-SWAPPABLE SOCKET & PRE-LUBED CUSTOM SWITCHES: This 75% mechanical keyboard is compatible with 3-pin or 5-pin switches, allowing you to personalize your keyboard. The switches are individually removable and can be replaced in seconds. The SKY81 keyboard utilizes MageGee's finely tuned switches, which are pre-lubricated at the factory and built to last up to 70 million keystrokes for responsive and creamy typing. STUNNING RGB BACKLIGHTING: This custom keyboard has 6 sets of default gaming backlight effects (FN + 1 ~ FN + 6), and 18 built-in backlight modes, as well as adjustable light brightness and speed. Bright static and dynamic lights shine in the dark, illuminating your desktop and enhancing the gaming experience. The switch on the left side of the keyboard turns the light off/on with one click. This 75 percent keyboard supports customized light effects and you can record by pressing FN + Back. MULTIFUNCTIONAL KNOB AND INDICATOR: The gaming keyboard features a metal knob for quick control of the keyboard lights and computer volume. By default, rotating the knob can adjust the backlight brightness, and pressing the knob can switch the lighting effects. Hold the knob for 3 seconds to switch to volume mode, then rotate it to adjust the volume and press it to turn on the media player. The 4 indicator lights on the right side can clearly display the real-time status of the keyboard.
