Our Verdict
Logitech G502 HERO
Razer Viper 8KHz
The Razer Viper 8KHz and the Logitech G502 HERO are both wired gaming mice, but the Razer performs better overall. It feels better built and has an ambidextrous design, and it's significantly lighter. It also has lower click latency and a higher maximum polling rate. On the other hand, the Logitech has a scroll wheel with L/R tilt inputs and a free-scrolling mode. It also has a sniper button and a thumb rest.
