The ASUS ROG Falchion RX Low Profile is a wireless mechanical keyboard that continues the ASUS Falchion lineup of compact gaming keyboards. This keyboard connects wirelessly with an included 2.4 GHz receiver or via Bluetooth. It has a touch panel for media controls and a physical toggle for switching between Windows and macOS compatibility modes.

It uses pre-lubed, low-profile RX ROG Optical switches—available in either linear or clicky varieties—and RGB backlighting that you can customize, among other settings, in the configuration software. It also comes with a plastic dust cover designed to sit over the front of the keyboard when not in use or for transit. While using the keyboard, you can move this plastic cover onto the back of the keyboard, and it has a set of large rubber feet to help prevent the keyboard from sliding around on desks.

Note: We experienced occasional key chatter (repeated keystrokes) while testing this keyboard. We've seen a small number of reports from the wider community experiencing this issue, but it's currently unclear how widespread it is and whether it's something you're likely to experience. We're closely monitoring the situation and will update our review as needed. For more details about this issue, see the Build Quality section below.

Differences Between Sizes And Variants

The ASUS ROG Falchion RX Low Profile is available with linear ROG RX Low-Profile Optical Red or clicky ROG RX Low-Profile Optical Blue switches. At the time of writing, it's only available in a white color option. We bought and tested the linear Red switch option.

You can see the label of our unit here.

Compared To Other Keyboards

The ASUS ROG Falchion RX Low Profile fills a specific niche as there aren't very many dedicated low-profile gaming options in the current market. Most low-profile gaming options that do exist are full-size models, like the Corsair K100 AIR, the Razer DeathStalker V2 Pro, and the Logitech G915 LIGHTSPEED. The Falchion RX Low Profile offers a compact (65%) alternative. Its smaller form factor not only means it takes up considerably less space in a desktop setup and leaves you more room for mouse movements but also makes it a much more portable option that's great for tournament players or anyone who frequently travels with their keyboard in tow. Also, this keyboard has a customizable touch bar with a small display. It keeps the face of the keyboard free of clutter and still provides dedicated media controls and backlighting brightness controls by default.

Unfortunately, we experienced some key chatter (repeated keystrokes) on the unit we bought and tested, so if you're interested in this board, we recommend purchasing either directly from ASUS or an authorized vendor with warranty support so you can RMA your keyboard if need be. This keyboard is also only available in a white colorway at the time of writing, which may not suit everyone's taste or desktop setup.

For more recommendations, see our picks for the best keyboards, the best wireless keyboards, and the best low-profile keyboards.

ASUS ROG Azoth

Both the ASUS ROG Falchion RX Low Profile and the ASUS ROG Azoth are compact, wireless gaming keyboards with roughly equivalent gaming performance. The Falchion has a slightly smaller 65% layout and a much slimmer low-profile design. It also has a touch bar. On the other hand, the Azoth has a larger 75% form factor, which includes dedicated arrow keys and a full function row. It has a customizable OLED screen and generally a more customizable design with a hot-swappable PCB and much more acoustic material inside the case, providing a more premium-feeling typing experience.

Logitech G915 LIGHTSPEED

The ASUS ROG Falchion RX Low Profile and the Logitech G915 LIGHTSPEED are wireless low-profile gaming keyboards with comparable raw performance. The biggest difference between them is their size. The ASUS is a much smaller compact (65%) model. It also supports Bluetooth and has a customizable touchpad to control things like backlighting and media controls. The Logitech, on the other hand, is a much larger full-size model. It has a set of physical button media controls and a scroll bar, as well as five dedicated macro buttons, which the Falchion lacks.

Corsair K100 AIR

The ASUS ROG Falchion RX Low Profile and the Corsair K100 AIR are wireless, low-profile gaming keyboards. The ASUS has a much smaller compact (65%) form factor and has a touch bar that you can customize using the configuration software. The Corsair is a significantly larger full-size model, but it's also noticeably thinner. It offers slightly better overall gaming performance and supports a higher maximum polling rate. It also has a digital screen display, dedicated macro keys, and dedicated physical buttons for media controls.

SteelSeries Apex Pro Mini Wireless

The ASUS ROG Falchion RX Low Profile and the SteelSeries Apex Pro Mini Wireless are both compact wireless gaming keyboards with similar raw gaming performance. THE ASUS is a slightly larger 65% model with a slimmer low-profile design and a customizable touch bar. Comparatively, the SteelSeries is a bit smaller, with a 60% form factor, but the standout difference is that it uses analog switches, which allow you to customize the pre-travel and reset distance of individual switches.

Razer DeathStalker V2 Pro

Both the Razer DeathStalker V2 Pro and the ASUS ROG Falchion RX Low Profile are wireless gaming keyboards with low-profile designs and roughly the same gaming performance. The standout difference between them is size: the Razer is a much larger full-size model, while the ASUS is a compact (65%) model. Otherwise, the Razer has physical button media controls, including a scroll bar. Comparatively, the ASUS has a customizable touch bar.

Build Quality
Keycap Material ABS

The ASUS ROG Falchion RX Low Profile has decent overall build quality. However, we encountered occasional key chatter (repeated keystrokes) during testing. This issue significantly impacts this keyboard's typing quality and gaming experience as unintentional repeat inputs occur on multiple keys and with unpredictable frequency. This issue is particularly unusual because the manufacturer advertises its switches as optical, which typically aren't prone to chattering. However, there's some language on ASUS's product page for these switches suggesting they may be a hybrid optical-mechanical design. This suggests it may not be an issue with the switches but rather a firmware issue that ASUS can address in a future update. We've only seen limited reports from the community about this issue, so it may only be a problem with a small number of units. We will continue monitoring the situation and update our review as needed. If you have this keyboard and have encountered key chatter issues, reach out to us in the comments.

Apart from the chatter issue we encountered on the unit we bought and tested, other build-quality elements of this keyboard are impressive. It has minimal deck flex, with a plastic bottom chassis and an aluminum top plate. Its ROG RX Low-Profile switches are pre-lubed from the factory and feel smooth overall. The keycaps are also very stable, and while they're made of ABS plastic (which often develops a slippery, shiny finish with extended use), ASUS indicates they have a UV coating designed to mitigate this. Unfortunately, while the stabilizers also do a great job of keeping larger keys stable, they aren't pre-lubed from the factory, so they sound somewhat inconsistent and produce faint rattling sounds. You can see a video of stabilizer performance here. That said, there are also two layers of silicone dampening foam inside the case that help to even out the overall sound profile and keep pinging noise to a minimum.

On the back of the board, there are a set of flat rubber feet and two rubber capped flip-out feet that all do a great job of keeping the board firmly in place on your desk without sliding around.

There's a mirrored finish panel on the top of the keyboard with Republic of Gamers branding and a touch control panel with dedicated media controls. However, this mirrored finish shows fingerprints easily and may be prone to scratches with rougher use.

Lastly, this keyboard also includes a plastic cover that you can place over the front or back. ASUS describes this as a dust cover. Unfortunately, it doesn't clip into place and is somewhat flexible in the middle, so it doesn't provide the same degree of protection a hard shell carrying case would. You can see images of the dust cover on top of the keyboard here and here.

This keyboard has a touch panel on the top left edge that, by default, provides dedicated media controls and allows you to adjust backlighting brightness. You can see an animation from ASUS's product page for this keyboard that demonstrates how this feature works.

The touch controls allow you to cycle between control modes with a button next to the touch panel and customize how the panel functions using the configuration software. During testing, we found that this panel works well but occasionally fails to register inputs.

This keyboard has a Caps Lock indicator light but supports other lock keys using hotkey combinations, including FN lock, Scroll Lock, and Windows lock, which provide on-screen notifications but don't have indicator lights.

A range of other hotkey combinations are supported, including battery life display, windows lock, RGB effect presets, etc. Many hotkeys are indicated with printed legends on the front edge of keycaps. To reference a full list of hotkeys, you can see a digital version of the user manual from ASUS's website here.

Altogether, this keyboard provides only satisfactory typing quality. While most aspects are impressive, we experienced occasional key chatter (repeated keystrokes) on the unit we bought and tested, which significantly reduced the quality of the typing experience. For more details, see the Build Quality section.

The key chatter issue aside, the switches are pre-lubed from the factory and feel quite smooth. Two layers of internal sound-dampening silicone foam help round out the sound profile and minimize the overall typing noise.

All keys are very stable, and keystrokes are very consistent, even if you hit a key on an edge or corner. The stabilizers also do a great job of making keystrokes on larger keys feel even and consistent. Unfortunately, the stabilizers aren't pre-lubed. They feel somewhat inconsistent, and they rattle slightly but noticeably while typing.

The ASUS ROG Falchion RX Low Profile uses Armoury Crate for customization. This software is reasonably straightforward and allows you to customize various expected settings, including key assignments, macros, power settings, and RGB lighting.

That said, as with software options from other major manufacturers, Armoury Crate is the source of widespread criticism from the broader community. While we didn't experience any issues during the testing of this keyboard, many users online criticize this software for being unnecessarily bloated, requiring frequent updates, and taking up disproportionate system resources, among other complaints. This software may be frustrating if you prefer more lightweight software options or no software at all.
