Our Verdict
Logitech G502 HERO
Logitech G903 LIGHTSPEED
The Logitech G903 LIGHTSPEED is a better gaming mouse than the Logitech G502 HERO; it's a wireless mouse with lower click latency. The G903 feels just as well made but has an ambidextrous design and can be used in any grip by any hand size, except for fingertip grip, which may be a little too large for smaller hands.
