Thursday, November 11, 2021

So legendary is the egyptian god Horus that his name features in many video games, namely Smite, the Horus Heresy: Betrayal at Calth, Downward Spiral: Horus Station and the Eye Of Horus, which is an old-school scrolling platformer game. Horus has also been immortalized on the new Redragon K621 Horus TKL, which is the tenkeyless version of the original Horus full size keyboard.

The K621 Horus TKL is, essentially, a smaller version with less keys on the board. There are a total of 87 physical keys, as well as 19 virtual keys for accessing various functions such as lighting controls, macros, multimedia functions (e.g. search, calculator and email). There are also 10 physical buttons located above the top row of keys. These buttons are made of rubber and have a mushy actuation. 


Five of those buttons are dedicated media playback controls (e.g. play/pause, skip tracks). The other five buttons G-keys (G1-G4) are designed to playback macros, as well as keyboard shortcuts. Macros are recorded on-board the K621 Horus TKL keyboard using the MR button. You can record up to 20 macros. Instructions on how to record macros can be found on the included user guide.

The Redragon K621 Horus TKL keyboard has a sloped base but the keycaps sit practically level with each other. The front row of keys measures 2.3cm high while the bottom row of keys measures 1.9cm high. With the feet risers elevated, the height of the top row of keys increases to 3cm high. The feet risers are sturdy, do not wobble and integrate thick grippy rubber.

The keycaps are made of double shot ABS so the legends are permanent and won't rub off. The white markings on the keycaps are pad printed so, they aren't permanent. The K621 Horus TKL keyboard measures 35.5cm long and 14.5cm wide, The frame thickness is 0.8cm thick. Weight is 591 grams. The K621 Horus TKLL is constructed similarly to the full size K618 Horus keyboard. The frame is made of plastic, while the top plate and textured wheel are made of metal. The wheel is designed for adjusting the volume, as well as scrolling through the backlighting effects.

There are 20 dynamic lighting effects, as well as 9 single static colors to choose from. The brightness, and lighting effect can be adjusted via the keyboard, using the fn key. You can also change the colors of some dynamic effects, as well as turn off the backlight of the keyboard. The K621 Horus TKL keyboard uses Redragon's own low profile hot swap mechanical switches, which can only be replaced with other low profile mechanical swtiches. Full size mechanical switches aren't compatible. The K621 Horus TKL keyboard uses dummy switches to stabilize the long keycaps.

There are 3 connection modes available: wired, Bluetooth and 2.4Ghz RF wireless via the included dongle, which stores magnetically underneath the keyboard. Bluetooth mode consumes more power than 2.4Ghz wireless but has the advantage of bluetooth multipoint, which lets you connect up to 3 devices at the same time. 


The K621 Horus TKL keyboard is equipped with the same 1900mAh battery found in the full size version (K618 Horus keyboard). With backlighting turned off, runtime is around 29 hours via 2.4Ghz. If use the keyboard 8 hours a day, you will only have to charge the keyboard every 2-3 days. As far as charging, it takes 6 hours to recharge the K621 Horus TKL, which is 3 hours longer than the full size version.
