Manufacturer description

Slip the Logitech G G703 Lightspeed into your hand and the first thing you notice is that it does not feel like a wireless mouse. LIGHTSPEED wireless delivers the pro-level responsiveness Logitech G built its esports reputation on, while the HERO 25K sensor tracks 1:1 from 100 all the way to 25,600 DPI with zero smoothing, filtering, or acceleration and 400+ IPS of tracking speed. That sensor is also 10x more power efficient than the previous generation, which is how a 95 g mouse runs up to 35 hours of continuous play with LIGHTSYNC RGB lighting enabled. If you would rather never think about…

Logitech's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.
