Our Verdict

Lofree Flow84/Flow100

AULA F99/F75

Both the AULA F75 and the Lofree Flow84 are compact 75% models with gasket-mount designs that lend a softer, slightly springy typing experience. The standout difference is their profile: the AULA has a fairly tall standard profile, while the Lofree has a much thinner, low-profile which makes it more portable and more comfortable to type on without a wrist rest. The Lofree also has considerably better and more premium-feeling build quality with an aluminum case. In contrast, the AULA supports 2.4GHz wireless in addition to Bluetooth, which provides significantly better wireless gaming performance.
