RK ROYAL KLUDGE RKS70 Review – Best Split Keyboard?

Quick Verdict

The RK ROYAL KLUDGE RKS70 earns its ergonomic stripes. That split layout genuinely relieved the shoulder tension I'd been ignoring for months, and the wrist rest is the real deal — thick, not some thin rubber afterthought. The RKS70 split keyboard hits a rare sweet spot: proper ergonomic engineering without the sky-high price of dedicated office gear. Tri-mode wireless, hot-swappable switches, and five macro keys round out a feature set that works equally well for a 10-hour coding session or an evening of gaming. If you're coming from a standard keyboard, there's a learning curve — but I'd call it worth it. 4.3 / 5.

What Is the RK ROYAL KLUDGE RKS70?

Let's be precise: the RKS70 is a 75% split mechanical keyboard with tri-mode wireless connectivity, hot-swappable PCB, integrated wrist rest, and per-key RGB. The brand, RK ROYAL KLUDGE, has been making mechanical keyboards for a while under a few different lines — the RKS series sits squarely in the ergonomic-gaming crossover space. Which is to say: it's built for people who take their typing seriously but also want something that looks at home on a gaming desk rather than a sterile office setup.

The split design is the headline here. The keyboard ships as two separate halves connected by a coiled cable. You can angle each half independently — inward, outward, tilted up or flat — thanks to eight adjustable feet (four per side). The integrated wrist rest is fixed to the main body and is noticeably thicker than the slim pads I've seen on competing models. On paper it sounds like a modest detail; in practice it changes the posture of your forearms in a way that registers within the first hour of real work.

Hands-On Review

I set the RKS70 up on a Wednesday afternoon — not a gaming session, just my regular work. The unboxing was straightforward: two halves, coiled cable, USB-C cable, 2.4GHz dongle, and a small manual. Connecting via Bluetooth to my laptop took about thirty seconds. No driver needed just to type.

By day two I stopped fighting the split and started appreciating it. I angled the left half slightly inward and kept the right half flatter — asymmetric, which sounds odd but felt natural. The brown switches are a safe choice: not as whisper-quiet as linears, not as vocal as clickies. They're the office-friendly option, and RK ships them pre-lubed, which cuts down on the scratchiness you sometimes get out of the box.

Here's what nobody mentions in the listings: the coiled cable between the halves is firm. It wants to spring back into a neutral position, which means it takes a few minutes to find the exact desk placement that keeps both halves stable. I ended up tucking the cable under a small notebook to anchor it — not a dealbreaker, but something to be aware of.

RGB is fine. Not groundbreaking — the light bar is subtle rather than the full-immersion kind — but the RK software lets you set per-key colors and a few reactive modes. I ran it on a slow color cycle for a few evenings and then switched to a static low-brightness blue, which is easier on the eyes in a dim room. Macro programming via the RK driver worked on my Windows desktop without issues; I mapped a few text-expansion shortcuts that would normally require third-party software.

Battery life held up well. I averaged about four days of eight-hour workdays with RGB on medium brightness before the indicator started blinking. Turn RGB off and you'll stretch that significantly. USB-C charging topped it up in under two hours.

Who Should Buy It?

Remote workers and developers spending 6+ hours at a desk will feel the ergonomic payoff most clearly. That split geometry genuinely reduces ulnar deviation — your wrists aren't splaying outward to reach a flat keyboard. The wrist rest makes long sessions more comfortable without the extra bulk of a separate pad.

Mechanical keyboard enthusiasts who want to experiment with hot-swapping without committing to a soldering setup. The PCB accepts a wide range of switches, so you can try reds, blues, or anything in between without modifying the board.

Productivity power users will appreciate the five macro keys and the ability to remap layers via RK software. If your workflow involves repetitive shortcuts, this board can trim seconds off every cycle — and they add up.

Skip this if you're after a compact travel keyboard — the split format needs desk real estate. Also skip it if you rely heavily on a numpad; the 75% layout omits it, and while the Fn-layer covers most functions, a dedicated numpad section it is not. Finally, if you share a workspace where a coiled cable and RGB lighting might distract colleagues, a quieter, non-split alternative makes more sense.

Alternatives Worth Considering

Keychron Q1 Pro: A premium option in the same 75% form factor with superior build quality and gasket mounting — but it's wired only in the base config, and the price is noticeably higher.

Microsoft Sculpt Ergonomic Desktop: If you want a proven ergonomic pedigree with a split layout, this is the reference point. The trade-off is it uses membrane/scissor switches, which won't satisfy mechanical fans.

Perigold Split Mechanical Keyboard: A more affordable split option with similar hot-swap capability. The build quality and software support don't quite match RK's, but the price undercuts the RKS70 for budget-conscious buyers.

FAQ

Final Verdict

The RK ROYAL KLUDGE RKS70 makes a strong case for split keyboards as a practical daily driver, not just an enthusiast novelty. The wrist rest alone justifies the switch if you've been typing on flat boards for years — your shoulders will notice within the first week. Tri-mode wireless and hot-swappable switches future-proof it in ways that most ergonomic office gear isn't. The 75% layout and coiled cable are honest trade-offs, not flaws. If you've been curious about split keyboards without wanting to spend $300+ on an experiment, the RKS70 is a reasonable entry point.
