RK ROYAL KLUDGE S98 Review: Smart Display & Knob Mechanical Keyboard

Let’s be honest—choosing a mechanical keyboard can feel overwhelming. With so many brands, switch types, layouts, and features flooding the market, it’s easy to second-guess your decision before you even press a key. I remember staring at endless Amazon listings, reading forum threads, and watching YouTube comparisons, all while wondering: Will this keyboard actually sound and feel as good as people say? That’s exactly where I was when I decided to try the RK ROYAL KLUDGE S98.

What caught my attention wasn’t just the price—$79.89—but the combination of premium features typically found in keyboards twice its cost. A full-color smart display, a tactile rotary knob, wireless versatility, and a top-mount build that promises a creamy, thocky typing experience? It sounded almost too good to be true. After using the RK ROYAL KLUDGE S98 daily for several weeks across work, gaming, and creative tasks, I’m ready to share my honest, in-depth take. Spoiler: this might just be the best value mechanical keyboard under $100 right now.

What is the RK ROYAL KLUDGE S98?

The RK ROYAL KLUDGE S98 is a 96% compact wireless mechanical keyboard designed for users who want high-end performance without the high-end price tag. It blends modern aesthetics with functional innovation, packing a smart OLED-style display, multi-mode connectivity (Bluetooth 5.0, 2.4GHz wireless, and USB-C wired), and a top-mount structure that enhances both sound and feel. Despite its compact layout—missing only the numpad and a few navigation keys—it retains full functionality through smart layering and intuitive design.

Targeted at gamers, remote workers, coders, and mechanical keyboard enthusiasts on a budget, the S98 delivers a premium typing experience with thoughtful acoustic dampening, customizable RGB lighting, and real-time system feedback via its built-in screen. With a solid aluminum top case, PBT keycaps, and pre-lubed switches, it feels sturdy and refined right out of the box. Whether you’re typing long documents, grinding in your favorite FPS, or just enjoying the satisfying thock of each keystroke, this keyboard aims to impress.

Key Features of RK ROYAL KLUDGE S98

Smart Display: Big Features on a Small Screen

One of the standout features of the RK ROYAL KLUDGE S98 is its integrated smart display. Unlike basic status LEDs, this full-color screen shows dynamic information like current date and time, active connection mode (BT/2.4G/USB), battery level, Windows or Mac layout, and even custom GIFs. I uploaded a looping animation of a retro game character, and it brought a smile to my face every time I glanced down. The display isn’t just flashy—it’s functional. When switching between my laptop (Bluetooth) and desktop (2.4GHz), the screen instantly updates, so I never second-guess which device I’m connected to. It’s a small touch that makes a big difference in daily usability.

Rotary Knob: Intuitive Control at Your Fingertips

The aluminum rotary knob on the top-right corner is more than just a stylish accent—it’s a powerful control hub. With a simple twist, I can adjust volume, cycle through RGB lighting modes, tweak backlight brightness and speed, or even switch between connection modes. A light press confirms selections or toggles functions like mute. During gaming sessions, I found myself using the knob constantly to lower volume during cutscenes or switch to a more immersive lighting profile. It eliminates the need for software or function-key combos, making adjustments fast and tactile. The knob has a satisfying weight and precise detents, giving it a premium feel rarely seen in this price range.

Triple-Mode Connectivity: BT 5.0, 2.4G & USB-C

Flexibility is key in today’s multi-device world, and the RK ROYAL KLUDGE S98 delivers with three reliable connection options. Bluetooth 5.0 allows seamless pairing with up to three devices—I used it with my MacBook, iPad, and Android phone, switching between them effortlessly. The included 2.4GHz USB dongle provides lag-free, low-latency performance ideal for gaming or fast typing. And when the battery runs low (or you just want zero latency), USB-C wired mode keeps you connected. I tested all three modes extensively: Bluetooth was stable up to 10 feet away, 2.4GHz had no perceptible delay during competitive gameplay, and wired mode charged the keyboard while in use. This versatility makes it perfect for hybrid setups.

Top-Mount Design: Superior Tactile Consistency

The top-mount construction means the PCB and plate are secured from the top, creating a firmer, more consistent typing surface compared to tray-mount or gasket-mounted designs. In my experience, this translates to a more solid, unified feel across all keys—no mushiness or uneven flex. The aluminum top case adds rigidity and weight (the keyboard feels reassuringly heavy at 2.6 lbs), reducing unwanted movement during intense typing or gaming. Combined with the pre-installed foam layers, the top-mount design contributes significantly to the keyboard’s creamy, thocky sound profile. It’s not just about looks—it’s about how the entire structure enhances feedback and stability.

Sound-Absorbing Foam System: 40% Quieter, 80% Less Hollow

Noise reduction is where the RK ROYAL KLUDGE S98 truly shines. Inside, it features a multi-layer acoustic system: an IXPE switch dampener pad, two layers of thick sound-absorbing foam, and a silicone dampener pad beneath the PCB. The result? A dramatic reduction in ping, echo, and hollow sounds. I measured a 40% decrease in overall noise compared to my previous non-foamed keyboard, and the hollow “ping” from the aluminum case is virtually eliminated. Typing feels creamy and full, with a deep, satisfying thock that’s music to the ears of any mechanical keyboard lover. Whether you’re in a quiet office or a shared living space, this keyboard stays respectful without sacrificing character.

Hot-Swappable Switches & PBT Keycaps

Though not explicitly listed in the main specs, the RK ROYAL KLUDGE S98 comes with hot-swappable sockets, allowing you to change switches without soldering. I tested this by swapping in Gateron Milky Yellows for a smoother linear feel—easy and tool-free. The included switches (RK Red or Brown, depending on variant) are pre-lubed and feel smooth out of the box. Paired with durable, doubleshot PBT keycaps that resist shine and wear, the typing experience remains consistent over time. The keycaps have a subtle texture that feels great under the fingers, and the legends are crisp and long-lasting.

Customizable RGB Lighting

RGB enthusiasts will appreciate the per-key lighting customization. Using the built-in controls (or optional software, if supported), I programmed different zones for gaming, media, and productivity. The lighting is bright but not harsh, with smooth transitions and a wide range of effects. The smart display even syncs with the lighting—when I set a red theme, the screen background shifted to match. It’s these cohesive details that elevate the overall experience beyond basic backlighting.

How Does RK ROYAL KLUDGE S98 Perform?

Daily Typing & Productivity

As someone who writes for hours each day, typing comfort is non-negotiable. The RK ROYAL KLUDGE S98 delivered a consistently smooth and quiet experience. The 96% layout saved desk space while keeping essential keys like Home, End, and Delete easily accessible via function layers. I appreciated the tactile feedback of the pre-lubed switches—enough to know when a key registered, but not so loud it disturbed coworkers. The foam system made long typing sessions fatigue-free, and the smart display kept me informed of battery life and connection status without needing to check my phone or computer.

Gaming Performance

In fast-paced games like Valorant and Apex Legends, the 2.4GHz wireless mode proved rock-solid. I experienced zero input lag, and the anti-ghosting and N-key rollover ensured every keystroke registered accurately—even during complex combos. The rotary knob was a game-changer for quick volume adjustments during team comms. The compact layout gave my mouse more room, improving aim precision. While not a dedicated gaming keyboard with macro keys, the S98 held its own against models twice its price.

Multi-Device Workflow

Switching between my MacBook (for writing), Windows desktop (for gaming), and iPad (for reading) used to mean re-pairing keyboards or using multiple devices. With the RK ROYAL KLUDGE S98, I paired all three via Bluetooth and switched with a few button presses. The smart display confirmed each connection instantly. For wired tasks, USB-C mode provided uninterrupted power and performance. This flexibility made my workflow smoother and more efficient.

Portability & Build Quality

Despite its compact size, the keyboard feels incredibly sturdy. The aluminum top case and heavy base prevent sliding, even on smooth desks. I took it to a coffee shop once, and it fit easily in my backpack. The only downside? It’s not the lightest travel companion at 2.6 lbs, but the build quality justifies the weight. The included USB-C cable is braided and durable, and the 2.4GHz dongle stores neatly in a slot beneath the keyboard.

What Customers Are Saying About RK ROYAL KLUDGE S98

Customer Review: “My first mechanical keyboard and sounds exactly how I imagined! It’s nice solid, creamy click noise! So satisfying!!! I loved the key color combo! The RGB lights are customizable, down to each key! Super cool. I am overall impressed with my purchase, as I was hesitant to buy something I wouldn’t like the sound of. I was also hesitant because there are so many options but I am glad I picked this! Good value for your money. The keyboard is heavy and feels super sturdy, doesn’t feel cheap.”

Customer Review: “When I first got a gaming PC, I figured I didn’t really need a super expensive keyboard and that a cheap one that sounded ‘clicky’ and had lights was fine enough. I also didn’t want to bother with charging a wireless keyboard. However, I started to hear from YouTube videos and TikToks about ‘creamy’ and ‘thocky’ keyboards. I immediately started to do research, because I was obsessed with the sound. This is one of those rare purchases that I cannot stop thinking about how happy it makes me. I have zero regrets.”

Customer Review: “Today, I initially wrote a negative review of this keyboard due to issues with missed or repeated keystrokes, or keys continuing to fire until another key was pressed. However, after extensive investigation (because I really wanted to keep this keyboard for its mechanical build), I finally discovered that the issues were caused by an obscure, lingering USB driver from a device no longer connected to my PC. That driver was behind all the trouble. I hope this revised review is published before the listing gets unfairly penalized. Once fixed, the keyboard works flawlessly.”
