It's the first to have a true 8,000Hz polling rate which sends 8x more data per second compared to other leading gaming mice, reducing input delay. The Viper 8KHz is available from January 28 for $80. The original Razer Viper was astonishing, so much so that it's been our best gaming mouse for competitive players ever since it launched. Razer doesn't stand still, though, and following from the wireless version comes the first update to the original model. The Razer Viper 8KHz is official and it's the fastest gaming mouse in the world.
