The Royal Kludge S98FR is a compact 96-key mechanical keyboard designed for users who want versatile connectivity and easy customization. It suits hobbyists who swap switches and need wireless options, as well as office users seeking a full layout in a smaller footprint. The keyboard offers multiple connection modes and a customizable interface, balancing portability with functionality.
The keyboard uses lubricated stabilizers to reduce rattle and create a smoother, quieter typing feel. The hot-swappable switches let users tailor the typing experience by choosing different switch types. The 96-key layout offers a near-full-size experience in a more compact design, which can benefit users who want dedicated arrow keys and a numpad without a large desk footprint.
Users can switch between Bluetooth 5.0 for wireless convenience, 2.4 GHz wireless for lower latency, or USB-C wired for stable connections and charging. The included 2.4 GHz dongle supports devices without Bluetooth. Battery life is supported by a 3750 mAh battery, though exact usage time is unknown.
