Manufacturer description

The Rii RK100+ is a full-size 105-key USB wired keyboard built for people who want mechanical-style feedback and rainbow lighting without a mechanical price tag. The layout measures 17.1 x 5.3 x 0.9 inches, so you get a dedicated numpad plus 11 multimedia key combinations for volume, playback, and shortcut control without giving up desk depth to a chunky case. Rainbow LED backlighting runs across the whole board, and a breathing mode is one Fn + light-key press away; three presses of the light button turn the backlight off entirely for daytime office work. Plug-and-play USB support covers…

SpecPicks Verdict

SpecPicks scored Rii RK100+ Multiple Color Rainbow LED Backlit Large Size 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. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Is the Rii RK100+ a real mechanical keyboard?

No. Rii states in its own product description that this is not a real mechanical keyboard; it is built to give a mechanical feeling. Expect membrane-style travel rather than discrete mechanical switches.

Does it work with a Raspberry Pi or an Android TV box?

Yes. Rii lists Raspberry Pi, Android TV boxes, HTPC, IPTV, and Smart TV among supported devices, alongside Windows 10, 8, 7, Vista, macOS, Chrome OS, and Linux.

How do I turn the backlight off?

Press the light button three times to turn the backlight off. Pressing Fn plus the light key instead switches the rainbow LEDs into breathing mode.

Does it have a number pad, and how much desk space does it need?

Yes, it is a standard 105-key full-size layout with a numpad. It measures 17.1 x 5.3 x 0.9 inches, so plan for roughly 17 inches of desk width.

What happens if I leave it idle for a while?

It enters sleep mode automatically after 10 minutes of no use. Any keypress wakes it and the backlights come back on.
