Razer Viper 8KHz Ultralight Ambidextrous Wired Gaming Mouse: Fastest Gaming Switches - 20K DPI Optical Sensor - Chroma RGB Lighting - 8 Programmable Buttons - 8000Hz HyperPolling - ESL Edition

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.

Held up really well so far. Very responsive and a simple, intuitive design

I hadn’t bought a new mouse in a very long time, but then I needed one for gaming. It is an excellent mouse. No complains. No issues. Just a lot of fun and that’s why I bought it in the first place.

I don't run Windows, so the Razer software is not being used, but just the hardware? It's sublime. Light weight, fills the hand well, doesn't die and double-click or miss clicks after a year like some other makers I could mention. Replaced multiple Logitech mice with Razers and haven't regretted it.

Excelente, la luz es fija, responde muy rápido y fácil de configurar...

Great mouse at an amazing price. Lightweight and perfect grip.

Don’t waste your money on this model; it’s trash. For starters mouse button 4 and 5 are flushed evenly with outer shell making it difficult to press it when needed during any FPS game. 8k polling is a joke and I have a 5950x cpu.

I mean.. it's a viper with ESL paint. It's as rock solid as the default one.
