Razer Viper 8KHz Ultralight Gaming Mouse

Amazing mouse. I have bought 4 of these. One was just a gift because I like it so much. The first one wore out with the mouse wheel essentially losing its ability to function after 12-15 months of using it 6 hours a day on average. The wheel will click but not properly scroll down or up without adding inappropriate inputs toward the opposite direction. In the items defence, I did not try to fix it. Mouse is incredible when it comes to tracking and the general feel. The 8khz polling rate genuinely seems to make a significant difference with my 240hz monitors. My wireless razer v3 viper with the 1khz polling feels significantly less responsive while still being a great mouse. The v3 viper and death adder MAY have solved the wheel issue as it is a different wheel.
