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.
