The RK84 is an 80% hot-swap keyboard that costs less than a good set of keycaps. Three connection modes — USB-C, Bluetooth 5.0 for up to three devices, and a 2.4GHz dongle — plus four switch options and a removable top panel add up to a feature list normally found two price tiers up. Tom's Hardware scored it two and a half out of five, and the gap between that and the enthusiasm elsewhere comes down to stabiliser rattle and a fiddly Bluetooth pairing routine.
Full review
An 80% layout with a removable top panel
The RK84 keeps the function row and arrows and drops the numpad, which is the layout most people actually use, and it does it in a case with a snap-off outer panel so the frame colour can be changed. Rickyspears rates the build as solid for the money with no flex under hard typing, while noting the white finish shows grime faster than a dark one would. The Tech Frontier's aluminum Pro variant weighs 1.08 kg and feels the part; the standard plastic version, at 803.5 grams, does not pretend to.
Bluetooth, dongle and cable, three devices deep
Three connection modes are the headline. Bluetooth 5.0 pairs up to three devices with function-key shortcuts to switch between them, the 2.4GHz dongle is the low-latency option, and USB-C works when the battery is flat. Techpp's review found the wireless stable across Windows, macOS and Android. Getting devices paired in the first place is the awkward part, because the process is manual, and it is the single most common complaint from new owners.
Hot-swap sockets for 3-pin and 5-pin switches
The board takes both three-pin and five-pin switches without soldering, which at this price is the feature that matters most: a switch set costs a fraction of the keyboard, so the typing feel is not locked in at purchase. Four RK switch options ship from the factory — a linear Red, a clicky Blue, a tactile Brown and a low-profile Red — and the double-shot ABS keycaps are thicker than the price suggests.
Stabilisers under-lubed enough to rattle
The Tech Frontier is clear about the weak point: the stabilisers are only lightly lubricated and the larger keys rattle. It is not unbearable and it is fixable with an hour and a tube of grease, but on a board sold partly on typing feel it is the thing that separates this from a more expensive keyboard.
ABS keycaps also shine with use, most visibly on the keys you hit hardest, and the lighting is even rather than vivid — fine on a desk, underwhelming next to a gaming board. Tom's Hardware's low score reflects a similar impatience with the details rather than with the feature list.
200 hours a charge with the lighting off
Battery life is quoted at up to 200 hours with the backlight off, which is weeks of normal use, and a full charge takes six to seven hours. The spacebar flashes to report charge state. Turn the lighting up and the figure collapses, as it does on every backlit wireless board, so the useful reading is that this is a keyboard you charge occasionally rather than nightly.
Strengths
- +Hot-swappable switches with four options (Red, Blue, Brown, Low Profile Red)
- +Multiple connectivity options including Bluetooth 5.0, USB-C wired, and USB receiver
- +Compact 80% layout with removable outer panel for a custom look
- +Solid build quality with magnetic feet and included accessories like switch puller
Watch-outs
- −Stabilisers ship under-lubed, so the larger keys rattle noticeably
- −Bluetooth pairing is a manual process that trips up first-time owners
- −ABS keycaps develop shine on the most-used keys, and the lighting is muted rather than vivid
How it compares
The Royal Kludge RK84 provides more connectivity options and hot-swappable switches than the Keychron Q1 HE, but it lacks the build quality and RGB lighting of the Keychron Q1 Max and Drop CTRL. While it's more affordable than the Mode SixtyFive, it doesn't offer the same level of customization or tactile feedback, making it a good budget-friendly option for users who don't mind a more basic setup.
