Manufacturer description
The Rii RK100 is a full-size 105-key wired USB keyboard built for shoppers who want backlit-gaming looks on an entry-level budget. Three LED backlight colors give you visibility in a dark room, and a breathing-light mode toggles on with fn plus the light key. Press the light button three times and the backlight turns off entirely. Eleven multimedia key combinations sit on the function row for volume, playback, and browser shortcuts, so you are not reaching for the mouse mid-track. The board measures 17.1 x 5.3 x 0.9 inches, a standard desktop footprint with a low 0.9-inch profile…
SpecPicks Verdict
SpecPicks scored Rii RK100 3 Colors LED Backlit Mechanical Feeling USB Wired… using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. Rii's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.
