RK Royal Kludge M100 Mechanical Keyboard Review: Gasket-Mount Thock Meets Budget Pricing

Can an $80 mechanical keyboard deliver gasket-mount thock, triple wireless connectivity, and a full number pad? The RK Royal Kludge M100 makes a strong case that it can.

The RK Royal Kludge M100 is a wireless mechanical keyboard featuring a compact 96% layout that keeps a full numpad while saving desk space. It packs pre-lubed cream switches, a gasket mount structure with five layers of sound dampening, and tri-mode connectivity through Bluetooth 5.0, 2.4GHz wireless, and USB-C.

I tested the M100 connected to my MacBook Air over Bluetooth and 2.4GHz, ran a full sound test, and swapped switches on camera. I put it through daily typing sessions covering coding, data entry, and general productivity.

The short version? This keyboard punches well above its price tag in most areas. But there are a few trade-offs worth knowing about before you pull the trigger.

What I Liked About the RK M100

The M100 delivered several standout features during my testing. Here are the highlights that earned it a spot on my desk.

Cream Switch Sound Test Delivers

The pre-lubed cream switches produce a deep, satisfying thock that I did not expect at this price. The gasket mount structure with five layers of sound-absorbing foam eliminates the hollow ringing you hear on cheaper boards.

Every keystroke has a dampened, thudding quality to it. The linear travel feels smooth from top to bottom with no scratchiness. Multiple reviewers have confirmed this keyboard sounds comparable to boards costing twice as much.

The spacebar is consistent too. There is no cheap rattle or variation in sound across different areas of the bar, which is a common weak point on budget keyboards.

Tri-Mode Wireless With Dual Knobs

Switching between devices is where the M100 stands apart. The left knob cycles through Bluetooth, 2.4GHz wireless, and wired USB-C modes without fumbling through keyboard shortcuts.

You can pair up to three Bluetooth devices simultaneously. I kept my MacBook Air on BT1, my iPad on BT2, and used the 2.4GHz dongle for my desktop. Switching between them takes about two seconds.

The right knob handles volume with satisfying tactile clicks and a mute function when pressed. The built-in mini LCD screen shows your battery percentage, active connection mode, and whether you are in Windows or Mac configuration.

96% Layout With Full Number Pad

The compact 96% layout keeps a full numeric keypad while trimming the keyboard down to about 15.5 inches wide. That is noticeably smaller than a standard full-size board.

For coders and data professionals who rely on number entry, this layout is a strong compromise. You get the numpad without sacrificing the desk space needed to keep your mouse at a comfortable distance.

The arrow keys and numpad sit right next to the main keyboard section without a gap. It takes a few days to adjust if you are coming from a traditional layout, but the muscle memory builds quickly.

400 Hours of Battery Life

The 8000mAh battery is enormous by keyboard standards. With the RGB backlight turned off, RK claims up to 400 hours of continuous use. With lighting on, expect around 60 hours.

In my testing, I went over two full weeks of heavy daily use before needing a charge. For a wireless keyboard, that effectively eliminates battery anxiety from your workflow.

The trade-off is charge time. Without fast charging support, a full charge from empty takes 6-7 hours through the included USB-C cable. Given the battery lasts weeks, this is a minor inconvenience.

Hot-Swappable PCB for Easy Mods

The hot-swap printed circuit board supports both 3-pin and 5-pin mechanical switches. Swapping is straightforward: pull the keycap, pull the switch with the included tool, and pop in a new one.

This opens up significant customization potential. If you prefer tactile or clicky switches over the stock linears, you can swap without soldering. The 5-pin support also means more stable switch seating compared to boards that only accept 3-pin.

What Needs Improvement

No keyboard at this price is without compromise. Here are the areas where the M100 falls short.

No QMK or VIA Support

Keyboard enthusiasts who rely on open-source firmware for advanced key mapping and macros will be disappointed. The M100 uses RK’s proprietary software, which limits customization compared to the community-driven QMK/VIA ecosystem.

For most users this will not matter. But if you want layered key remapping or cross-device profile syncing through open tools, this is a notable gap.

RGB Software Limited to Windows

The RK customization software only runs on Windows. Mac and Linux users are stuck with the default lighting effects accessible through keyboard shortcuts.

You can still change backlight brightness, cycle through preset patterns, and toggle RGB on or off from the keyboard itself. But fine-tuned color customization and macro programming require a Windows machine.

Snap-On Case Design

The M100 uses a snap-on case that requires prying tools to open. If you want to add custom foam, swap stabilizers, or make internal modifications, the process is more frustrating than keyboards with a simple screw-off design.

The good news is the M100 sounds solid out of the box. Most users will never need to open the case.

Slow Charging Speed

Despite the impressive 8000mAh battery capacity, there is no fast charge support. A full charge from empty takes 6-7 hours through USB-C. RK also recommends against using fast-charging cables or wall adapters as a precaution.

Given the battery lasts two-plus weeks, this is manageable. But it means you cannot top up quickly if you forget to charge over the weekend.

How It Compares

The mechanical keyboard market under $100 is competitive. Here is how the M100 stacks up against three popular alternatives.

RK M100 vs Keychron C3 Pro

The Keychron C3 Pro runs about $45 and uses Gateron switches that many consider smoother than RK’s cream switches. However, the C3 Pro is wired-only and uses a tenkeyless layout without a numpad.

If wireless connectivity and a number pad matter to your workflow, the M100 justifies the extra cost. If you only need a wired board and prioritize switch feel above everything else, the C3 Pro is worth considering.

RK M100 vs Redragon K552

The Redragon K552 Kumara is a proven budget pick at around $35 with years of community validation behind it. It uses Outemu switches in a compact tenkeyless form factor.

The K552 trades features for reliability and price. It lacks wireless capability, hot-swap support, and a numpad. For a first mechanical keyboard where you want to spend as little as possible, the K552 delivers. For a more complete feature set, the M100 offers significantly more.

RK M100 vs Royal Kludge RK61

The RK61 comes from the same manufacturer at $40-50 in a 60% ultra-compact layout. It offers Bluetooth and hot-swap but sacrifices the function row, numpad, and dedicated arrow keys.

Choose the RK61 if portability is your priority. Choose the M100 if you need the numpad and prefer a larger typing surface. Both share RK’s connectivity strengths and hot-swap flexibility.

Final Verdict

The RK Royal Kludge M100 delivers an impressive combination of features for an $80-90 mechanical keyboard. The gasket-mount typing feel, hot-swap flexibility, and triple wireless connectivity put it ahead of most competitors in this price range.

I am giving the M100 a 4.1 out of 5. The sound quality and feature density are excellent for the money. The lack of QMK/VIA support, Windows-only software, and potential long-term reliability questions from broader RK product history keep it from a higher score.

Bottom line: If you want a wireless mechanical keyboard with a numpad, gasket mount thock, and hot-swap capability under $90, the RK Royal Kludge M100 is one of the strongest options available. It earns a confident recommendation for budget-conscious buyers who value features over brand prestige.
