Our Testing Experience

First Impressions

When I first took the Rii RK100+ out of the box, I was surprised by its size. It’s quite large compared to my usual keyboards, but the rainbow backlight instantly caught my eye. Setting it up was super easy — just plugged it into my PC’s USB port and it worked right away without needing any extra drivers. The keys have a nice mechanical feel, even though it’s not a true mechanical keyboard. I liked that it felt sturdy and looked colorful on my desk.

Daily Use

Using this keyboard daily for both work and casual gaming was a smooth experience. Typing felt comfortable thanks to the key spacing and the soft click sound. The rainbow backlight wasn’t just for show — it actually helped me see the keys better in low light, especially during late-night work sessions. Switching to the breathing light mode using the fn + light key combo was fun and gave my setup a cool vibe. I also appreciated that it worked well with my Windows 10 laptop and even my Raspberry Pi.

Key Features in Action

The rainbow backlight was definitely my favorite feature. It’s great that you can turn it off by pressing the light button three times, which helps save power when you don’t want any distractions. The multimedia keys were handy too, letting me adjust volume and control music without leaving my game or work screen. The keyboard’s large size made it easy to use all keys without feeling cramped, and the wired USB connection meant no lag during gaming or typing.

Long-Term Performance

After a few weeks of daily use, the Rii RK100+ still feels solid and responsive. The keys haven’t become sticky or worn out, and the backlight still shines bright. I haven’t noticed any connection issues or delays, which is impressive for this price range. Overall, it’s been a reliable keyboard for both work and light gaming, and I feel like it offers great value considering its features and build quality.
