The performance of the Razer Viper Mini is excellent. While its max CPI isn’t as high as the other mice in the Viper lineup, it should still be more than sensitive enough for most people. It’s also not quite as adjustable, as it steps in increments of 100, instead of 50 like most other Razer mice. The polling rate can be set to 125, 500, or 1000Hz, though since it’s a wired mouse and you don’t need to worry about battery life, you’ll likely want to use it at its highest polling rate anyways. Like with the Razer Viper Ultimate, we noticed a much higher CPI error when using the mouse slowly, at just over 7%, while we registered around -3% error when using quick movements.
