RK ROYAL KLUDGE S98: problems, parts and running costs
Checked: 2026-10-19
Summary
A 96%-layout (98-key) tri-mode wireless mechanical keyboard with hot-swappable switches, a TFT display and a control knob. The dominant complaint is battery life with RGB on: one reviewer charges every other day against an advertised ~30-hour figure. At around $70 retail the spec sheet is competitive; no warranty information was readily available and no major outlet has reviewed it.
Common problems and fixes
- Battery drains fast with backlight on — Sypnotix measured well under the advertised 30-hour figure and charges every other day; the battery also drains in standby. Workaround: charge every other day or run USB-C wired. [2]
- Keycap material disputed — RK claims PBT double-shot; TechNuovo identified ABS double-shot with a semi-rough texture. No fix; decide based on how much keycap feel matters. [1][3]
- No shine-through legends — the RGB is south-facing, so light glows around the keycaps instead of through them. No fix available. [3]
- Slow GIF transfer to the display — custom GIF upload works but transfers slowly. No fix reported. [3]
- Numpad footprint — the compressed layout makes the board less ideal for competitive gaming setups with tight desk space; it is geared more toward productivity. [3]
- No warranty information found — neither the manufacturer page nor the manual listed warranty terms. [1][8]
Parts and consumables
Yearly running cost
Not enough data. The keyboard has no priced consumables — the only running cost is charging the internal battery — and no electricity or part-price data was recorded. [1]
When it is a good buy
Listed retail prices: $69.99 (Sypnotix, 2025); about £75 on RK’s UK website (TechNuovo, 2025); 109,999 KRW, about $78 (RK Japan); ₹9,999, about $120 (RK India). At about $70 the feature set — tri-mode wireless, hot-swappable switches, top-mount dampening, a display with a knob, USB passthrough — is competitive, and the board makes sense when wireless flexibility and a compact numpad matter more than all-day battery with RGB on. No alternatives were compared in the record; RK’s RK61, RK96, L98 and S85 are mentioned only as distinct boards not to confuse with the S98.
