Our Verdict
Keychron K2 (Version 2)
ROYAL KLUDGE RK61
The ROYAL KLUDGE RK61 and the Keychron K2 (Version 2) are both compact, wireless keyboards emphasizing mobile use. The Keychron is slightly bigger because it has a function row, navigation buttons, and dedicated arrow keys, but that means the ROYAL KLUDGE is smaller to carry around. The Keychron has RGB backlighting, and while the version of the ROYAL KLUDGE that we tested has blue backlighting, there's an RGB variant. Typing feels better on the Keychron because the keys are more stable, but since you can get each keyboard in a variety of switches, the typing quality depends on the ones you get.
