Asus ROG Falchion RX Low Profile

Manufacturer: Asus

The Asus ROG Falchion RX Low Profile is a compact 65% gaming keyboard built for users who want a low-profile mechanical feel with wireless flexibility. It connects via USB, 2.4GHz wireless, or Bluetooth 5.1, giving users a range of options depending on their setup. The keyboard comes in white, with a case constructed from plastic and aluminum, and features RGB backlighting alongside a small built-in display. It weighs 595 g and includes adjustable feet, though no wrist rest is bundled in the box.

The keyboard uses ROG RX Low-Profile optical linear switches with a 1 mm actuation distance and a light 40 g actuation force, designed for fast and consistent keystrokes. The switches are not hot-swappable, and features such as rapid trigger, adjustable actuation, and analog input are not present. Keycaps are PBT with a DSA profile in a standard ANSI layout, and the detachable cable adds convenience for transport and storage. The polling rate runs at 1000 Hz, N-key rollover is supported, and media functions are accessible via the Fn key rather than dedicated keys.

Pros
  • Supports USB, 2.4GHz wireless, and Bluetooth 5.1 connectivity, giving users flexibility across different setups without being locked to a single connection method
  • The detachable cable simplifies storage and transport, and reduces wear on the port over time
  • N-key rollover ensures every simultaneous keypress is registered, which is particularly relevant in fast-paced gaming scenarios
  • The built-in display adds on-board functionality for monitoring or customization without relying solely on software
  • PBT keycaps with a DSA profile offer durability and a uniform typing surface across all rows
  • Adjustable feet allow the keyboard angle to be modified to suit different typing preferences
Cons
  • The switches are not hot-swappable, meaning switch replacement requires soldering and cannot be done quickly or easily by the user
  • Advanced input features such as rapid trigger, adjustable actuation, and dual actuation are absent, which limits the keyboard's appeal for users who rely on these capabilities
  • Media functions are only accessible via the Fn key layer, with no dedicated media keys available
  • No wrist rest is included, which may be a drawback for users who type for extended periods
  • The keyboard is not designed for Mac, restricting its out-of-the-box compatibility for macOS users
  • There is no USB passthrough port, reducing desk connectivity options for users who would benefit from it
Who is this for?

This keyboard is well suited to gamers and typists who want a compact 65% layout without sacrificing wireless flexibility, thanks to its tri-mode connectivity across USB, 2.4GHz, and Bluetooth 5.1. The low-profile optical linear switches with a 1 mm actuation distance and 40 g actuation force cater to users who prefer light, fast keystrokes, and the inclusion of N-key rollover ensures input accuracy during demanding gaming sessions. The detachable cable and compact footprint also make it a practical option for users who move between workspaces or travel with their setup regularly.

Who is this NOT for?

Users who frequently swap switches or want to experiment with different switch feels will find the non-hot-swappable design a significant limitation, as replacing switches requires soldering. The absence of rapid trigger, adjustable actuation, and dual actuation makes it unsuitable for competitive players who depend on these advanced input features for a performance edge. Additionally, the lack of dedicated media keys and Mac compatibility out of the box narrows its appeal for content creators or macOS users looking for a seamless experience without workarounds.
