Our Verdict

Razer Viper Ultimate

Logitech G502 LIGHTSPEED

The Razer Viper Ultimate is a better FPS gaming mouse than the Logitech G502 LIGHTSPEED, but both are very good, versatile mice. The Razer is smaller and much lighter, with an ambidextrous design that suits a fingertip grip, except if you have smaller hands. It has two side buttons on each side of its body, while the Logitech has an unlockable wheel and an additional sniper button on the side. The Logitech is big and heavy, with an ergonomic design and a thumb rest. It should be better suited for people with larger hands.
