ULTIMATE G903 is our most advanced and fully featured gaming mouse. Featuring 1 ms LIGHTSPEED wireless, G903 delivers competition-grade performance, responsiveness and accuracy. Combined with POWERPLAY, G903 operates wirelessly with infinite power, never needing a charging cable. LIGHTSPEED WIRELESS Logitech G invented LIGHTSPEED wireless technology to deliver the ultimate in high-performance wireless gaming. NO WIRE. NO LIMITS. LIGHTSPEED wireless technology is as fast or faster than many wired gaming mice. And that was the required benchmark for LIGHTSPEED viability. The only satisfactory result is the total freedom of wireless with absolutely no compromises. 1 MS WIRELESS ACHIEVED Logitech G engineers worked through a complete end-to-end technology optimization from sensor to firmware, circuitry to antenna. We tested and refined each component, focusing on the slowest link until nothing was slow. 1. SPI: Sensor peripheral interface is highly optimized for maximum processing speed and efficiency to track motion precisely.2. MCU: Microcontroller unit translates data from the SPI, via enhanced firmware, faster than ever before.3. RFIC: Radio frequency integrated circuit transmits MCU data robustly and reliably via fine-tuned electrical pathways.4. RF antenna is designed specifically for LIGHTSPEED for absolute minimum impedance and maximum signal strength.5. Nano receiver connects discretely via USB and is fully capable of transmitting at a report rate of 1,000 Hz (1 ms) to the PC. WIRED AND WIRELESS Plug in the data and charging cable to seamlessly switch between wireless and wired modes without interrupting your game. Use the included USB adapter to keep your LIGHTSPEED USB transceiver nearby to quickly switch between wired and wireless modes. LIGHTWEIGHT CONSTRUCTION Every component of G903 has been optimized to reduce weight while maintaining strength, from thin wall molding to a spoked hyperscroll wheel design. The result is a fully-loaded wireless mouse that weighs in at only 110g. Maximize comfort over extended periods of use and feel quicker response to motion. POWERPLAY READY Add POWERPLAY, the world''s first wireless gaming mouse charging system, to keep G903 charged even while you play. Never plug in your mouse again or worry about whether your mouse is charged. Play unlimited. Play advanced. COMPETITION OPTICAL SENSOR G903 comes equipped with the PMW3366 optical sensor with zero smoothing, filtering or acceleration across the entire DPI range (200-12,000DPI), delivering exceptional tracking accuracy and consistent responsiveness at any speed. For even better accuracy and speed, use the surface tuning in Logitech G HUB to maximize your sensor. POWER-EFFICIENT TECHNOLOGY Exclusive clock-tuning technology significantly reduces sensor power draw, so you can play for a continuous 32 hours on a single charge. Battery Assistant in Logitech G HUB keeps you informed about your charge level and gives you an estimate of your remaining battery life. ULTIMATE CUSTOMIZATION Configurable ambidextrous buttons, custom RGB lighting, 11 programmable buttons, on-the-fly DPI shift settings, onboard memory and more. G903 does it all with Logitech G HUB.
