Rii RK105 wired keyboard and mouse bundle with three-colour backlight (UK layout)

What it is and what it’s for

The Rii RK105 is a wired keyboard and mouse set designed for day-to-day office and home use, using a full-size, standard UK layout. You’re not buying this for portability or a minimalist desk, you’re buying it for something you can plug in and leave there—typing documents, browsing, spreadsheets, and general computer work—without fuss.

On paper, the main “hook” is the three-colour backlit keyboard plus a breathing backlit mouse. There are also different light behaviour modes, which can be handy if you sometimes work with the lights down. The set is aimed at people who want familiar layout comfort and a straightforward USB wired connection more than they want premium materials or a complex setup.

If you’re the sort of buyer who just wants a reliable desk combo, RK105 should make sense. If you care about silent key travel or a super-precision mouse sensor experience, it may feel a bit more mid-range than you’d hoped—especially given the description doesn’t position it as a high-end gaming peripheral.

Key features you’ll actually notice

The keyboard is full size with 105 keys and a standard UK layout, plus multimedia shortcuts (12). It uses a chiclet-style key design described as quiet and softer, with a responsive feel—though the Enter key is specifically noted as still having a “clacking” sound.

The backlight is three-colour with three adjustment modes. There’s a breathing light mode, and there’s also a single-colour stay-on option where you can adjust brightness via FN + PGDN/PGUP. If you prefer a low-key look, you can turn the backlight off by clicking the Light key three times. It’s the sort of detail that can matter in shared rooms or if you’re sensitive to desk lighting.

The mouse is described with a smooth body and a breathing backlit effect. It also includes a non-slip silicone roller, and it’s pitched as suitable for office use. The mouse being wired is useful for stability, but it also means you’ll want the cable reach to be workable for your desk setup.

How the lighting works (and where it can be limiting)

Backlit peripherals are a personal preference. Here you get enough control to avoid the “always distracting” problem: breathing mode, stay-on with brightness adjustment, and an off option via the Light key. The idea, as described, is to be easier on your eyes.

That said, it’s worth keeping expectations realistic. Backlight modes are mainly about atmosphere and visibility, not performance. If you’re buying because you want ultra-quiet typing or a workstation that feels premium, the description doesn’t strongly suggest that. It’s more of a practical desk bundle that adds a bit of visual flair.

Also, since both keyboard and mouse are wired, you’re relying on nearby USB ports and cable routing. It’s ideal for a fixed desk, but less ideal if you frequently move between laptops.

Everyday use experience: a quick example

Imagine you’re working in the evening on a Word document or an online form. With the backlight on, you can see the keys without turning on a bright overhead lamp. You can start in breathing mode, then switch to a single-colour stay-on if you prefer a steadier look.

Later, if you need to focus and reduce distraction, you can press the Light key three times to turn the backlight off. The foldable feet on the keyboard are included to support a more comfortable typing angle during longer sessions—small detail, but it can noticeably affect posture.

For spreadsheets and navigation, the full-size layout reduces the “where is that key?” learning curve, especially if you’re used to a standard UK arrangement.

Who it suits, and who should look elsewhere

It’s a solid pick if you want a straightforward wired keyboard and mouse for office and home work, you prefer a full-size keyboard, and you value backlighting with multiple modes. It suits people who like familiar key placement and want multimedia shortcuts without needing to hunt for extra functions.

It may not suit you if you: - need a wireless setup or portability between devices - expect a silent, office-grade whisper-typing experience (Enter is described as still clacking) - want a specialist performance mouse feel rather than a practical office mouse

Worth considering if your priority is “plug in and get on with it” and you’re happy to treat cables as part of desk life.

Tech overview (so you can check fit quickly)

From the information provided, the kit includes a keyboard and a mouse, both USB wired. The keyboard uses a standard UK layout with 105 keys and 12 multimedia shortcuts. It’s described as having UV light-transmitting characters for anti-fading and oil-proof keycaps, and it uses an ABS build. The mouse is described as smooth-bodied and comfortable to hold, with breathing backlight.

Compatibility is mentioned in broad terms: it’s described as working with laptops, desktops, computers and PCs of Windows 98/XP/7/8/10/Vista, and Mac OS. That’s helpful, but “works with” doesn’t always mean every feature behaves identically across all systems, so it’s sensible to check your exact use case before committing.

What’s in the box and what to check before buying

The packing box is described as including a keyboard, a mouse, and a manual. Before you buy, it’s worth double-checking two practical things: you’ll have an available USB port for both devices, and your desk has enough cable space for your preferred positioning.

If backlighting matters to you, note that the keyboard lighting can be switched off by pressing the Light key three times—so it’s not an “always on” situation. But if you’re extremely sensitive to light even in off/standby scenarios, you may want to consider other non-backlit layouts.

Is it worth it?

The Rii RK105 wired keyboard and mouse bundle is most appealing when you want an all-in-one desk setup: full-size UK layout, backlit keyboard with adjustable modes, and a breathing backlit mouse, all via a simple USB wired connection. For office tasks, home admin, and general computer use, it does the job without demanding a learning curve.

You should consider skipping it if you want wireless convenience, very quiet typing, or a mouse experience that’s focused on advanced precision rather than everyday office control. If you’re after a straightforward USB desk duo with a bit of light customisation for evening work, it’s the kind of purchase that can quietly make your daily setup more comfortable.
