Quick verdict

Which one should you get?

Get the

Ajazz AK820 Pro

Hot-swappable

Build quality in the bottom 50% of 75% boards under $100.

Rules this board out

  • South-facing LEDs. Shine-through legends stay dark, and some sculpted keycaps can clip the LED.
  • No ISO layout. ISO-DE, UK, and other ISO variants are not offered.
  • No numpad.

Get the

Keychron B2 Pro

Build quality in the bottom 10% of 96% boards under $100.

Rules this board out

  • Switches are soldered. Swapping them means soldering.
  • Low-profile switches and keycaps only. Standard MX keycaps will not fit.
  • Compact full-size layout. The numpad is present, the gaps of a full-size board are not.
