Our Verdict
Razer Viper V2 Pro
G-Wolves HSK Pro 4K
The Razer Viper V2 Pro and the G-Wolves HSK Pro 4K are high-performance, wireless gaming mice. The G-Wolves features an unconventional shape that's only suitable for a fingertip grip, but it's significantly lighter than the Razer. The Razer has a larger symmetrical shape suitable for various grip types and hand sizes.
