Logitech G305 LIGHTSPEED: Manufacturer specification · With one AA battery; mouse alone is 75 g. Battery type changes operating weight.

Logitech G305 LIGHTSPEED: Manufacturer specification · Left, right, wheel click, forward, back and DPI cycle; excludes the underside power switch.
14.6 mm apart

Choose the grip, then check the connection. Left-side thumb controls are not a mirrored left-handed layout. Check the receiver or USB connection, battery requirements and your preferred shape. DPI is tracking resolution, not an accuracy score; no gaming winner is inferred.
