Our Verdict

Logitech G903 LIGHTSPEED

Logitech G305 LIGHTSPEED

The Logitech G903 LIGHTSPEED is a better wireless gaming mouse than the Logitech G305 LIGHTSPEED. It feels better built and has a more comfortable design. It can also be used by almost any hand size in every grip type, except for small hands with a fingertip grip. It has more programmable buttons, and you can unlock the scroll wheel for infinite scroll. On the other hand, the G305 is a smaller and more lightweight mouse that may be easier to travel with.
