Why it's worth it
The G Pro X TKL runs Logitech's LIGHTSPEED 2.4GHz protocol, which matches wired report rates rather than approximating them. It's the board to get if you want your desk cable-free without giving up competitive response, and the GX Red linears are a safe, familiar choice.
Wireless gaming keyboards stopped being a compromise, and this is the proof. LIGHTSPEED runs at a 1ms report rate over its own 2.4GHz dongle, which is the same figure a wired board hits at 1000Hz polling. Bluetooth is there as a fallback for a tablet or a laptop, and USB is there when the battery dies. Battery life is rated up to 36 hours at default RGB settings, so you're charging roughly once a week.
Logitech built this around what tournament players ask for: standard key spacing and layout so third-party keycap sets fit, a game mode that kills the Windows key, media controls and a volume roller. The GX Red linears are light and smooth with no tactile bump, which is what most competitive players use. Dual-shot PBT keycaps mean the legends survive the shine that eats ABS caps.
