TL;DR

Tom's Hardware called the RK84 'Lots of Features, One Serious Flaw' (the 2.4 GHz wireless). MakeUseOf and Gadget Explained both name it an 'excellent entry-level' first mech. Reddit treats it as the gateway: every other r/MechanicalKeyboards thread that mentions it is someone modding it, swapping switches, or moving on from it to their next board. The $70 hot-swap wireless that does almost everything okay and one or two things genuinely badly.

Verdict: Buy

Pros

  • +Hot-swap PCB, Bluetooth + 2.4 GHz + USB-C, dual USB passthrough — all under $80
  • +Plastic case 'feels sturdy and has very little flex' (High Ground Gaming) — better build than the price suggests
  • +Double-shot ABS keycaps will outlast cheaper rebrands
  • +Becomes a great keyboard with $30-40 of mods (lubed stabs, fresh switches, foam) — common modding target
  • +Three connection modes work; multiple owners report years of trouble-free use

Cons

  • −Tom's Hardware verdict: 'the 2.4-GHz option is nearly unusable and the software is awful' — biggest published red flag
  • −Royal Kludge software is universally panned: 'looks old and is light on features' (HGG); 'feels like a half-baked solution' (MakeUseOf)
  • −Battery longevity is a real concern — owner-reported swelling at 2 years; r/RoyalKludge has a thread documenting this
  • −Firmware updates have bricked at least one user's keyboard — 'don't upgrade firmware if no charge or necessarily needed' (owner)
  • −MacOS layer needs Karabiner Elements or a custom config to get function keys behaving like a Magic Keyboard

The Royal Kludge RK84 is the keyboard you'll end up modding. That's not me being cynical — it's literally the most common framing on r/MechanicalKeyboards. The most-upvoted RK84-specific thread (177 upvotes) is titled "I spent 100$ Modding a 50$ Keyboard: Royal Kludge RK84." Other RK84 threads are people swapping in Holy Pandas, building Mac configs, or moving on to their next board. It's the gateway drug at the budget tier — what the Q2 is at the premium tier.

I read four substantive tech-media reviews (Tom's Hardware blocked WebFetch, but the title and subhead are quotable), pulled seven Reddit threads, and catalogued nine YouTube reviews including 135K-view and 98K-view long-forms (transcripts unavailable — see sources at end). The picture is: a great budget chassis with two real flaws Tom's Hardware was right to call out, and a community that mostly mods around them.

What you're actually getting

Tri-mode wireless, hot-swap, dual USB passthrough — all under $80. Gadget Explained captures the spec-sheet appeal: "The RK84 keyboard features two USB passthrough ports, which is rather unique because a lot of keyboards don't even have a USB pass-through." And: "It has three connection modes, including two wireless modes (2.4Ghz dongle and bluetooth) and a wired mode via USB-C cable." (review) The pass-through is genuinely useful for keeping a wired mouse or USB drive on the same cable run.

A plastic build that punches above its price. High Ground Gaming reviewer Cody D. Campbell: "The board has plastic housing, but it feels sturdy and has very little flex to it." (review) MakeUseOf's Jowi Morales adds the form-factor angle: "The compact 75% format saves desktop space and makes it perfect for carrying around." (review)

Hot-swap with switches that are good enough to start. Gadget Explained: "The TTC-K brown switches are also hot swappable with a other switch brands, including Gateron and Cherry MX, which is a huge plus." Reddit owner u/koalatykaty (11 upvotes, in the holy pandas thread): "I got this keeb for $80 on amazon and would have to say it's a pretty solid board for the price point. i got it with blues which are iirc are TTC brand?"

How it actually performs in owners' hands

The mod-it pattern dominates. From the 177-upvote modding thread, u/leeys- (7 upvotes): "Me too fellow rk84 owner! The keycaps, lube, switches, foam mods I did are already twice of what the keyboard cost. Did you change the stabs? I find the stock are great after lubing with 205g0 and didn't find the need to change it." That's the consensus — stabs are passable after lube, switches and caps are the upgrade targets. MakeUseOf agrees: "The RK84's stock keys are perfect for typing, gaming, and everyday use."

The stepping-stone pattern is everywhere. The 567-upvote "From RK84 to KBD67 Lite" thread title says it. Within it, u/GordonThreeman: "sorry for going a little off topic but how did you like your rk84? was there any problem that caused you to switch off it, or just felt like upgrading?" The fact that this question comes up so often is itself the answer — people enjoy their RK84, then trade up.

The RK84 Pro vs base discussion gives a useful direct comparison from u/HappyPessimist33: "I had been using the standard rk84, then the rk100 rgb. Only spent a few hours with [the Pro] last night but it's pretty solid. No USB hub like on the standard rk84. It's got a nice weight to it but the standard rk84 was built a lot better than I was expecting. The standard rk84 I had would shut off the LEDs after like 5 seconds of inactivity." u/robotphood: "With a few sound mods it sounds surprisingly good (deep/thoccy)."

Where it falls short

Tom's Hardware's title says it. "Royal Kludge RK84 Review: Lots of Features, One Serious Flaw" — and the subhead spells it out: "the 2.4-GHz option is nearly unusable and the software is awful." Two complaints in one sentence, both grounded across other reviewers.

The software is universally panned. High Ground Gaming: "RK software looks old and is light on features." MakeUseOf: "The app itself doesn't feel well built. It feels like a half-baked solution made just so that people can customize their devices." Royal Kludge has done little to fix this. Owner u/feijao_arroz on Reddit confirmed it got worse: "I think the files don't work anymore because they changed the file format to a proprietary one: .rkf (for the profiles) and .rkm (for the macros)." Most owners ignore the software entirely and remap via the keyboard's hardware shortcuts.

Battery swelling is a real long-term failure mode. The r/RoyalKludge battery swelling thread documents an OP whose battery swelled after "just a little over 2 years of usage." u/rouge2909: "Glad you removed it, that fcked up my KB and got leds busted and columns not working same Rk84 not buying again." u/PanJackson with the safety angle: "Don't throw that in the trash and do not keep it in your house. Those can explode and catch fire without any warning." Mitigation: dispose of swelling batteries through e-waste; if your RK84 is past 2 years, periodically check the case for bulging.

Firmware updates can brick the keyboard. From the Keys not working thread, u/Joshslyr71: "Mine problem 'Fn+ScrLK and Ins' doesn't work. after pressing 'Fn+Space' for 3 to 4 sec and when the lights turned blue, resets my RK84 KB. Works fine now. I highly suggest don't upgrade firmware if no charge or necessarily needed. You may end up with bricked KB." Same thread, u/Sharp-Economics-6662 captures the cumulative frustration: "What a pos how can they keys on a fucking keyboard not work." Other owners report dead keys solved by swapping a switch (u/calmstoic2000: "The 'y' key wasn't working for me. None of the solutions here worked. Replaced the key with another one that comes in the box. Works perfectly fine now.") — which is at least the upside of the hot-swap PCB.

MacOS support is rough. The Best MacOS Config thread (90 upvotes) exists because the stock Mac mode is broken. OP: "the default MacOS mode in the RK84 is not that good, so I decided to create a config for it. For the function and multimedia keys to work simultaneously I had to use the Win (Fn + A) mode. If you use the Mac mode you will not be able to use the multimedia keys sadly." u/acwyau88's fix (4 upvotes): "I downloaded an app called Karabiner Elements and now all the function keys work exactly like my Magic Keyboard 2....media controls work without using the FN keys." Mac users: budget for Karabiner setup time on day one.

Should you buy it?

Buy if you want a $70-80 wireless hot-swap 75% as your first mechanical, you're willing to live with bad software (or ignore it entirely), and you understand 2.4 GHz wireless is the sketchy connectivity option (Bluetooth and wired are fine). MakeUseOf: "At less than $80, you're getting a fully-featured 75% wireless mechanical keyboard with a load of customization options." Their verdict: "This makes the Royal Kludge RK84 an excellent entry-level mechanical keyboard for those new to the bespoke keyboard hobby." Gadget Explained agrees: "The Royal Kludge RK84 is one of the best first time mechanical keyboards you can get for a regret-free transition."

Skip if you want a Mac-friendly board out of the box (Keychron K-series), if reliable 2.4 GHz wireless is non-negotiable for gaming, or if you want a board that won't tempt you into modding (it will).

Wait if you can find an Aula F75 at the same price — the F75 has gasket mount and a foam stack the RK84 doesn't, though Aula's QC is more variable. Different trade-off, similar price.

Frequently Asked Questions

Is the RK84 worth it as a first mechanical keyboard?

It's the most-recommended budget hot-swap wireless first board for a reason: $70-80 gets you tri-mode connectivity, hot-swap PCB, decent stabs, and double-shot keycaps. Gadget Explained: 'The Royal Kludge RK84 is one of the best first time mechanical keyboards you can get for a regret-free transition.' MakeUseOf agrees: 'an excellent entry-level mechanical keyboard for those new to the bespoke keyboard hobby.' The catch is that the software and 2.4 GHz wireless are bad enough that Tom's Hardware put 'One Serious Flaw' in the title.

How bad is the 2.4 GHz wireless really?

Bad enough that Tom's Hardware made it the headline complaint: 'the 2.4-GHz option is nearly unusable.' High Ground Gaming flagged the same issue from a different angle: 'The connection was a little spotty when the dongle was connected directly into the IO port.' The workaround most owners use is to put the dongle in a USB extension cable away from the keyboard, or just use Bluetooth (which works fine) or wired (always reliable).

Should I worry about battery swelling?

It's a real risk on a 3+ year horizon. The r/RoyalKludge battery swelling thread documents an OP whose battery swelled after 'just a little over 2 years of usage.' Comments include u/rouge2909: 'Glad you removed it, that fcked up my KB and got leds busted and columns not working.' This is not unique to RK — NuPhy has the same problem on the Air75 V1 — but it's a known failure mode. If your RK84 is over 2 years old, monitor for case bulging.

Should I update the firmware?

Cautiously. From the Keys-not-working thread, u/Joshslyr71: 'I highly suggest don't upgrade firmware if no charge or necessarily needed. You may end up with bricked KB.' If everything works, leave it. If you must update, do so plugged in and fully charged.
