Our Verdict
Endgame Gear OP1 8k
Razer Viper 8KHz
The Razer Viper 8KHz and the Endgame Gear OP1 8k are wired gaming mice with symmetrical shapes and 8000Hz maximum polling rates. Both mice offer exceptional raw gaming performance. On the one hand, the Endgame Gear uses SPDT mechanical switches and has lower click latency. It's also significantly more lightweight, making it easier to move more quickly and accurately. It's also noticeably smaller, so it isn't as accommodating for larger-sized hands. On the other hand, the Razer has a fully ambidextrous design with a pair of side buttons on either side. It also uses optical switches and has slightly better overall sensor performance.
