RedThunder's keyboards & mice lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Key Features

  • 【Triple Mode Multi Device】It can not only get rid of the cord shackles for a fast typing experience, but also meet the extreme speed experience of wired mode when charging. With the flip of 2 switches on the top, you can seamlessly switch between different devices in WINDOWS, MacOS, 2.4G wireless, wired and BT modes, giving you the freedom to move between different spaces. (Note: FN+Q/W/E to switch between BT1 /BT2/BT3 device. Not recommended for accountants or other numerical workers).
  • 【Hot Swappable Switches】The hot-swappable keyboard is a game-changer! Built-in hot-swap PCB lets you replace 3-pin or 5-pin switches without soldering, giving you a wide choice. Built-in pre-lubricated pink shafts make typing smooth and comfort. Comes with spare pre-lubricated shafts and a key puller for you to experiment with different switches freely to find the perfect feel for your typing style or gaming needs
  • 【Satisfying Creamy Sound】Gasket keyboard truly shines with its distinctive construction and superior performance in mechanical keyboards. Compared to Top-Mount Design, the Gasket Design has five-layer shock absorption and a single-key positioning plate. The unique design allows for a more even keystroke feel on the keyboard and enables full-key anti-ghosting. This results in a softer and more comfortable typing experience. It will be ideal for gamers and typists alike.
  • 【Full RGB & 4000mAh Battery】The K65 mechanical keyboard with 1.68 million RGB colors and a rechargeable 4000mAh battery can light up diverse atmospheres. Use FN combinations, CNC knob, or software to set RGB light modes (like rhythm lights), color, speed, and brightness. FN + TAB can adjust side lighting modes. South-facing LEDs meet most keycap lighting requirements, including side-engraved ones. A charging indicator shows power needs & status, ensuring you never miss a charge for long-lasting use (opt for the original charging cable or a qualified data-capable one to charge via a computer's USB port).
  • 【75% Professional Gaming Keyboard】The 75% compact layout keyboard saves more space over full-size, keeps arrow keys for gaming. Dual-color PBT keycaps are richer in color without fading, and stepped keycaps ensure that long typing times are more comfortable and less fatigued. Two-stage foot support adapts to multiple angles. Suits intense gaming or different work with efficient, user-friendly design. Side-printed characters are not suitable for novice users.
  • 【Multi-function Control Knob】This 65% wireless gaming keyboard‘s CNC knob can switch gaming mode and office mode by long pressing for about 5 seconds. In gaming mode, you can rotate the knob to adjust the brightness of the lights, and click the knob to switch the lighting effects easily; in office mode, rotate the knob to adjust the volume, and click the knob to play or pause.
