SpecPicks Verdict

SpecPicks scored Redragon K673 HE Wired Hall-Effect Rapid Trigger Magnetic Gaming… using a rating × review-volume × price-fit model applied to published specs and reviews across the keyboards & mice category. Redragon's keyboards & mice lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for keyboards & mice of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Key Features

  • One-Knob Simplicity - A single control knob adjusts backlight brightness and media playback, so you manage lighting and volume without memorizing extra key combos.
  • Built for the Stop-and-Shoot Moment - Next-gen UltraMag POM magnetic switches sense keypresses without physical contact, so your peek-and-fire timing in Valorant, CS or Apex lands exactly when you mean it.
  • Dual-Module Floating Structure, Noise Dampening - An anti-wobble independent switch-plate design paired with dampening layers gives a soft, silky, Hi-Fi bounce instead of a harsh, rigid clack.
  • 8,000Hz Hyper-Polling, Rapid Trigger & PRCS - Wired connection transmits inputs up to 8x faster than standard keyboards, while dynamic key activation cuts redundant keystrokes during quick direction changes.
  • Software-Powered Precision Tuning - Save multiple actuation profiles between 0.1mm and 3.4mm and calibrate the magnetic switches through the desktop or web-based driver, so your setup stays consistent across games.
