Our Verdict

Keychron K5 Max [K1 Max, K3 Max, etc.]

Lofree Flow 2

The Keychron K5 Max and Lofree Flow 2 are both low-profile wireless mechanical keyboards. The Keychron is available in a wide range of sizes and key layout configurations. They also have better raw gaming performance, and they're available with full RGB backlighting, although the keycaps lack shine-through legends. By comparison, the Lofree keyboards are only available in three size variants, but they have noticeably better build quality and feel much more premium overall, with slightly more refined typing quality. They only have white backlighting, but the keycaps include shine-through legends, which makes them easier to read in darker rooms.
