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.
