mice work, advancing one of the most basic things that we do as gamers... clicking! Instead of refining traditional mechanical switches, Logitech G has replaced them with a Haptic Inductive Trigger System (HITS), delivering a fully analogue, ultra-responsive clicking experience built for speed, precision, and control. HITS technology uses inductive analogue sensing instead of physical switches, allowing instant actuation and reset, while reducing click latency by between nine and 30ms. It introduces ten adjustable actuation points, five rapid trigger reset stages, and six levels of real-time haptic feedback – all configurable through Logitech’s G HUB software. The PRO X2 also features the HERO 2 sensor with 100 to 44,000 DPI, zero smoothing or acceleration, speeds up to 888 inches per second and 88G acceleration. LIGHTSPEED wireless delivers up to 8,000Hz, with 60 to 90 hours battery life, POWERPLAY compatibility, and a lightweight 61-gram ergonomic design. It’s stacked!
