Redragon K585 RGB: problems, parts and running costs

Checked: 2026-10-19

Summary

The K585 is a budget one-handed mechanical keyboard (42 keys, Outemu switches) whose weak point is software: the companion app is buggy and required for macros, and some owners hit freezes or disconnects during play. It costs nothing to keep running — the wired version draws power from USB and the wireless PRO recharges over USB-C, with no consumables and no subscription. It is an easy buy at $20 or less, still reasonable up to about $35, and hard to justify above $50.

Common problems and fixes

Companion software is buggy and can fail to detect the keyboard — TechPowerUp and XDA report poor Windows scaling, cut-off menu text and a thin set of options; a Tom’s Hardware forum user reported the app not detecting the K585 PRO at all. Workarounds are reinstalling the app and keeping the keyboard in wired mode, since on the wireless version the software only works while it is plugged in. US warranty terms are unconfirmed; the manual covers failures due to electrical circuit problems, and Redragon’s South Africa store lists 18 months for the ELITE PRO. [1][2][3][7][9][15][19]
Keyboard freeze or disconnect during play — a Reddit owner reported held keys (like “W” to run) stopping mid-game, and a Redragon shop customer went through two units that started “going crazy and turning on and off”. No defect rate has been published, so treat this as a known risk rather than a measured failure rate. [5][8]
Wrist rest magnets let go — the magnetic rest holds during normal use but detaches if you lift the keyboard by the wrist rest; carry it by the keyboard case. [4]
ABS keycaps shine over time — the stock caps are ABS plastic; no replacement cap pricing has been reported. [1]
Fixed typing angle and a real adaptation period — there are no feet, so the angle never changes; one owner rotated the keyboard 20° and remapped WASD to EDSF to reach the thumb cluster comfortably. [1][11]
No QMK/VIA support — the Sonix controller means a 2021 QMK feature request was closed without implementation, so custom firmware is off the table. [10]

Parts and consumables

Switches (K585 PRO and later variants) — hot-swappable, so a dead switch can be pulled and replaced without soldering; the original wired DITI’s hot-swap status is unconfirmed. No replacement switch pricing was reported. [6][12][13]
Keycaps and stabilizers — ABS keycaps, OEM profile, Cherry-style stabilizers; no parts catalog or aftermarket pricing was found for this model. [1]

Yearly running cost

Effectively nothing. The wired K585 DITI is USB bus-powered, the wireless PRO recharges from its 3000 mAh battery over USB-C, and there are no consumables and no required software subscription. [1][6][15]

When it is a good buy

Redragon’s own shop lists the K585 PRO wireless at $49.99 and has sold it on sale at $17.50 (65% off); Newegg lists the Blue-switch PRO at $49.99; the South Africa store lists the ELITE PRO at R 999.00 (all prices as gathered 2026-10). At or under $20 the PRO is an easy buy for a one-handed mechanical keypad; $21–35 is still good value; $36–50 is fair; above $50 the software and reliability issues are harder to justify. [12][16][19]
