The F75 is the cheapest way I know to get the full modern keyboard formula in one box: a gasket mount instead of a plate screwed rigidly to the case, factory-lubed switches, plate-mounted stabilisers and a foam stack that removes the hollow rattle most budget boards have. The 75% layout keeps the function row and arrows while dropping the number pad, which is the single change that makes a desk feel bigger. The aluminium knob is a small thing that turns out to matter once you use it for volume.
It shares the desk with the F2022. The F75 is the board for when I want the desk cleared and the arrow keys kept; the F2022 covers the occasions when I need the number pad.
Aula's software is proprietary — no QMK, VIA or ZMK on this generation, so everything goes through the manufacturer's app and it only does its job properly on Windows. The ABS case and keycap legends wear faster than PBT doubleshot on the competition. Keycap colouring and knob position vary between regional revisions, so what you get depends on which SKU is in stock.
