Ajazz AK820 Pro

6.3/10verdict: good, not the best

The Ajazz AK820 Pro is for people who want a compact 75% wireless keyboard with hot-swap switches and a gasket mount. It suits desk users who want a choice of Bluetooth, 2.4GHz or USB-C connections. It is a better fit for ANSI users and those happy with Ajazz's own software than for anyone who needs QMK/VIA.

AULA F75

6.3/10verdict: good, not the best

The AULA F75 is a 75% wireless, hot-swap keyboard for people who want a compact board with Bluetooth, 2.4GHz and wired options. It suits buyers who will lube a stabiliser if needed and who mostly use it with the lights off. It is less suited to anyone who wants an all-metal case or has to rely on the companion software.
