Razer Viper V4 Pro Wireless Esports Gaming Mouse

Overview

The Razer Viper V4 Pro is a 49 gram wireless esports mouse with an 8000Hz polling rate, a 50K DPI optical sensor, and up to 180 hours of battery life. It suits competitive PC gamers who want the lightest, lowest latency wireless mouse Razer sells, at a premium price.

Razer built this around Gen-2 HyperSpeed Wireless, which claims 55 percent lower latency than the previous generation while still supporting true 8000Hz polling, and buyers can trade battery life for polling rate depending on how they set it up. An optical scroll wheel and Gen-4 optical switches replace the mechanical parts that usually wear out first on a mouse. It ships with grip tape, a wireless dongle, and a USB A to C cable.

What buyers say

From Amazon customer reviews.

Reviewers are close to unanimous on build quality, sensor accuracy, and battery life, with several long term users calling it their go to mouse over other flagships they own. The most common caveats are the high price, a scroll wheel that a couple of reviewers call the weakest part of the mouse, and one buyer noting the 50K DPI figure is more marketing than something most players actually use.

Performance notes

The Focus Pro 50K optical sensor tracks up to 930 IPS and 90G of acceleration, and Frame Sync aligns sensor data with the PC to cut down on latency during fast flicks. Battery life scales with polling rate: Razer rates it at up to 180 hours at 1000Hz or up to 45 hours at 8000Hz, so a player can choose longevity or maximum responsiveness rather than being locked into one setting. The optical scroll wheel and Gen-4 optical switches are built to avoid the mechanical wear that eventually causes double clicks on older mice.
