Our Verdict

Logitech G502 HERO

Logitech G703 LIGHTSPEED with HERO Sensor

The Logitech G703 LIGHTSPEED with HERO Sensor and the Logitech G502 HERO perform similarly as they have the same sensor but are different in design. The G502 is slightly bigger and has a more aggressive gamer-centric look, with twice the amount of buttons. The G703 is smaller and lighter and features a rather sleek and simple design. It’s also more versatile, as you can use it wirelessly with its USB receiver.
