Our Verdict

NuPhy Air75 V3

Lofree Flow 2

The NuPhy Air75 V3 and the Lofree Flow 2 are wireless, low-profile mechanical keyboards. The NuPhy has a plastic case but boasts full RGB backlighting, wider aftermarket switch compatibility, and slightly better gaming performance overall. The Lofree, on the other hand, is available in three different sizes and has somewhat better and more premium-feeling build quality with a solid aluminum case design. However, it only has white backlighting and uses relatively more limited VIA configuration software.
