Our Verdict

Logitech G703 LIGHTSPEED with HERO Sensor

Logitech G403 HERO

The Logitech G703 LIGHTSPEED with HERO Sensor and the Logitech G403 HERO have very similar designs and perform almost the same. However, the G703 can be used wirelessly with its USB receiver, while the G403 is a wired-only mouse. Both options are somewhat lightweight, very comfortable, and well-suited for a palm grip. They use the same sensor and have the same number of buttons.
