Keychron Q4 Hot-swappable Wired Mechanical Keyboard with RGB LED|Barebone with Knob Version|for Windows and Mac|mini Layout (61 Keys)|Aluminum Frame (Grey,Q4-A2)

The Q4 is created with a 6063 aluminum CNC machined body, polished, anodized and sandblasted finish, and twenty-four manufacturing processes. A real sturdy, heavy and premium build quality.
The gasket design provides the board with a nice, flexible typing feel and a satisfying typing sound. In addition to the gaskets on the plates, the Q4 features silicone pads between the top and bottom cases to significantly reduce the sound resonance between the metals and reduce the noise of the impacted metals.
The Q4 hot-swappable PCB allows you to easily swap out switches without disassembly and de-soldering, so you can use your favorite switches or try out new switches without the risk of damaging the keyboard. The PCB supports both 3 pin and 5 pin MX mechanical switches.
The screw-in design increases stability and makes it easy for changes and upgrades. More precise craftsmanship makes the silver-plated stabilizers more stable and less wobbly. The big keys (space bar, shift, enter, delete) typing experience is more stable and smooth and rattling is significantly reduced. The Q4 also support third-party stabilizers including Cherry or Durock.
A unique RGB feature where the LEDs are located at the bottom of the switch rather than the top, which make them appear brighter because they are facing the typer. It is also good for the PBT, Cherry profile, and non-shine-through keycaps which are popular for customized keycaps.
