Manufacturer description

The Rii RK100+ is a full-size 104-key membrane keyboard built for the mechanical-feel look at a budget price. What you get is a white ultra-slim chassis measuring 17.1 x 5.3 x 0.9 inches with rainbow LED backlighting across five mixed colors, toggled with FN plus the backlight key and dimmed with FN plus Page Up or Page Down. FN plus F1 through F12 unlocks the multimedia layer for volume, playback, and shortcut keys, so you are not reaching for the mouse mid-game. A non-slip base keeps the 622g board planted during fast key presses, and an automatic sleep mode drops the backlight after 10…

SpecPicks Verdict

SpecPicks scored Rii RK100+ White Gaming Keyboard 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.

Frequently Asked Questions

Is the Rii RK100+ a real mechanical keyboard?

No. Rii states plainly it is a mechanical-feeling keyboard, not a true mechanical one. The switches imitate mechanical travel and sound rather than using individual mechanical switches.

Does the backlight work on Mac or Linux?

No. Rii specifies the backlighting does not support macOS or Linux. The keyboard itself still types on Mac, Chrome OS, and Linux, but the rainbow LEDs only light up on Windows systems.

How do I turn the rainbow lighting on and adjust brightness?

Press FN plus the backlight key to toggle the rainbow breathing effect on or off. FN plus Page Up increases LED brightness and FN plus Page Down decreases it.

What size is the keyboard and will it fit my desk?

It measures 17.1 x 5.3 x 0.9 inches (43 x 13.6 x 2.6 cm) and weighs 622g. That is a standard full-size 104-key footprint with a numpad, in an ultra-slim 0.9-inch profile.

Why does the backlight turn off while I am using my PC?

The keyboard enters sleep mode after 10 minutes without a keypress and shuts the backlights off. Pressing any key wakes it and restores the lighting immediately.
