Our Verdict

Logitech G305 LIGHTSPEED

Logitech G203 LIGHTSYNC

The Logitech G305 LIGHTSPEED and the Logitech G203 LIGHTSYNC are very similar gaming mice but have a few standout differences. The LIGHTSYNC scores better for gaming across the board, but it's wired only, has a narrower CPI range, and while it has a somewhat better click latency, most people likely won't notice a difference. Despite scoring lower, the LIGHTSPEED may be a better gaming mouse for some. It connects wirelessly with a USB receiver but is heavier since it's powered by an AA battery. It doesn't have RGB lighting, but this may not bother some people. Both mice are well-suited for all hand sizes using a fingertip grip, and only those with larger hands may find a palm or claw grip uncomfortable.
