What we like about Redragon K621 Horus TKL Wireless

  • Excellent value for money compared to high-end low-profile alternatives
  • Versatile 3-mode connectivity (Bluetooth 5.0, 2.4GHz wireless, and USB-C wired)
  • Comfortable low-profile design with a sturdy aluminum top plate
  • Highly customisable and vibrant RGB lighting with onboard controls
  • Dedicated media controls and a multi-purpose volume scroll wheel
  • Good battery life, with some users reporting up to 9 days or more on a single charge
  • Hot-swappable switches (though limited to specific low-profile Redragon brands)

What we don't like about Redragon K621 Horus TKL Wireless

  • Inconsistent 2.4GHz wireless connection with reports of signal drops and lag
  • Volume wheel can feel stiff and requires multiple scrolls for significant adjustments
  • Proprietary switch design limits third-party replacement options
  • Software can be buggy and may fail to detect the keyboard or lead to bricking issues
  • Build quality feels slightly 'cheap' or 'flimsy' to some users compared to premium brands
  • Reported issues with repeating characters or keys sticking over time

Verdict

The Redragon K621 Horus TKL is a versatile, low-profile wireless mechanical keyboard featuring a compact 87-key tenkeyless layout and tri-mode connectivity (2.4GHz, Bluetooth 5.0/3.0, and USB-C). It is equipped with hot-swappable linear red switches with a short 1.2mm actuation distance, 20 preset RGB lighting modes, and dedicated media controls including a volume/brightness scroll wheel and five on-the-fly macro keys. Main advantages include its ultra-thin ergonomic design, broad compatibility across Windows and Mac, and a 1900 mAh battery that supports up to five switchable devices. However, some users have reported occasional wireless signal drops during heavy use and noted that the scroll wheel and secondary rubberized buttons can feel somewhat flimsy or wobbly.
