The Logitech G102 LIGHTSYNC is a wired gaming mouse built around a simple principle: accurate tracking, responsive clicks, and a design that stays out of your way during play. At its core is a gaming-grade optical sensor covering 200 to 8,000 DPI, paired with a 1,000 Hz polling rate that reports your movement to the PC every single millisecond. Whether you're dragging crosshairs across a wide monitor or making micro-adjustments at close range, the G102 keeps up without hesitation. The 6-button layout is deliberately straightforward. Primary buttons use a mechanical spring tensioning system with a rated lifespan of 10 million clicks, delivering a sharp, consistent click feel that holds up over time. The layout includes side buttons for forward/back navigation and a DPI cycle button, all re-assignable through Logitech G HUB software. LIGHTSYNC RGB illumination runs across three independent lighting zones around the rear of the mouse, selectable from approximately 16.8 million colors. Lighting effects include color wave, breathing, audio visualizer, and screen sampler — and can be synchronized with other LIGHTSYNC-compatible Logitech devices. At 85 grams with a 2.1-meter USB cable, the G102 is light enough for quick movements without sacrificing stability. Onboard memory stores your custom profile — sensitivity levels, button assignments, and lighting — so your settings travel with the mouse to any PC, no software required. Key Features: 8,000 DPI Gaming-Grade Optical Sensor Adjustable from 200 to 8,000 DPI across five selectable sensitivity levels, the sensor delivers precise, consistent tracking throughout its entire range. Cycle through your saved DPI profiles on the fly using the dedicated button on the mouse, without needing to open any software. 1,000 Hz Polling Rate — 1ms Response Time The G102 reports its position to your PC 1,000 times per second, which is eight times faster than standard office mice. The result is near-zero input lag — your on-screen cursor mirrors your hand movement in real time. Mechanical Spring Button Tensioning — 10 Million Click Rating The primary left and right click buttons are tensioned with durable metal springs, which maintain consistent actuation force and deliver a crisp tactile response. The 10-million-click lifespan rating means the feel stays the same whether you're on your first session or your thousandth. LIGHTSYNC RGB with 3 Independent Lighting Zones Unlike budget mice that use a single lighting area, the G102 splits its RGB illumination across three separate zones along the rear band. Each zone can be set independently, and all three can sync with audio input, screen colors, or other LIGHTSYNC-compatible Logitech devices. Onboard Memory for Profile Storage Your personalized settings — DPI levels, button mappings, and lighting configuration — can be saved directly to the mouse's built-in memory using Logitech G HUB. Plug the mouse into any computer and your preferences load automatically, with no software installation needed. 6 Fully Programmable Buttons Beyond the two main click buttons and scroll wheel, the G102 includes dedicated side buttons and a DPI shifter. All six buttons can be remapped through Logitech G HUB to custom commands, macros, or shortcuts tailored to your game or workflow. Symmetrical Design at 85g The compact, symmetrical form factor (116.6 × 62.15 × 38.2 mm) works well with palm, claw, and fingertip grip styles. The lightweight build reduces hand fatigue during extended sessions without compromising control. 2.1-Meter USB Cable The generous cable length provides freedom of movement across a range of desk setups. The wired connection also ensures zero wireless interference and no battery management — plug in and play.
