Noise level depends heavily on switch choice; the silent option is genuinely quiet, but the board still retains recognizable mechanical character with other switches.
Onboard storage is repeatedly praised for holding many profiles or lighting layers.
USB passthrough is regularly described as a convenient extra.
Per-key lighting control is explicitly supported and treated as a premium feature.
Reviews explicitly call out the lack of per-key RGB programming, so lighting control is broad but not granular.
The 4000Hz polling rate is a headline feature, but reviews split between future-proof enthusiasm and skepticism about real-world gains.
Multiple reviews cite 1000Hz wired and 2.4GHz polling, with lower Bluetooth polling, which aligns with its work-first but gaming-capable positioning.
The K100’s weight and full-size build make it a poor choice for portable use.
Portability remains a clear strength thanks to the compact low-profile build, though several reviews note the V3 is heavier than some earlier or rival options.
