Reviewers call out the cleaner font and bright, crisp legends as improvements.
Legend styling is divisive: reviewers note clean alignment and shine-through support, but several dislike the aggressive ROG font.
Dedicated G-keys, Elgato support, and broad remapping options make macro control one of the K100’s strengths.
Macro and advanced mapping support are available through Gear Link, including macros and more advanced remap functions.

Materials are generally well regarded, especially the metal top construction, though some reviewers still note mixed-material tradeoffs at this price.
Dedicated media buttons and rollers are seen as useful, polished, and in some cases highly configurable.
Media control is well covered through the touch area and physical controls, though some users find the touchbar less intuitive than the wheel.

The 4000Hz polling rate is a headline feature, but reviews split between future-proof enthusiasm and skepticism about real-world gains.
Polling rate support is a headline feature, with multiple reviews calling out the 8K capability.
The K100’s weight and full-size build make it a poor choice for portable use.
Portability is helped by the included carrying case, which reviewers call out as a useful travel extra.
Large onboard profile storage and easy profile switching are mentioned often.
Profiles can be stored in the cloud, giving the board practical profile management across multiple systems.
Rapid Trigger support is heavily praised and positioned as one of the keyboard’s standout competitive features.
Reliability is mixed because a few reviews report hardware or crash issues even though others praise the hardware overall.
Reliability looks strong from the available evidence, with wear-free switch design and stable in-game performance both highlighted.
Lighting customization is deep and flexible, though some reviews find the setup process clunky.
