Pros and Trade-offs

Your need for a numpad is the deciding factor. Choose the Keychron C2 Pro if you require a full-size keyboard for office, data, or content creation work. Opt for the Keychron C3 Pro if you want a more compact TKL board, value the gasket mount for a softer typing experience, and plan to use shine-through keycaps with its north-facing RGB.

  • +Features south-facing RGB LEDs, which avoid interference with Cherry-profile keycaps.
  • +Includes screw-in stabilizers, which can offer more stability than standard plate-mounted ones.
  • +Uses OSA-profile double-shot PBT keycaps according to its vendor page.
  • +Offers three adjustable typing angles (4.8°, 7.8°, 10.2°).
  • −Larger and heavier (975g, 436mm long) than the TKL model.

  • −Lacks a numpad, which can be a drawback for data entry.
  • −North-facing RGB can cause interference with certain Cherry-profile keycaps.
  • −The vendor description does not mention screw-in stabilizers.
