Our Verdict

ROYAL KLUDGE RK61

AULA F99/F75

Both the ROYAL KLUDGE RK61 and the AULA F75 are entry-level wireless mechanical keyboards. The Royal Kludge (RK) has a slightly smaller 60% form factor and feels marginally better built. On the other hand, the AULA has a larger compact (75%) form factor with dedicated arrow keys and a function row. It also has a volume knob which the RK lacks. Unfortunately, it feels a bit cheaper overall, and the buying experience is a lot more confusing, with inconsistent documentation and some uncertainty about which components you'll receive. It also has a significantly better typing experience with a very soft gasket mount and extremely smooth pre-lubed switches and stabilizers.
