Our Verdict
Razer Viper Mini
Mad Catz R.A.T. 2+
The Razer Viper Mini is a better wired gaming mouse than the Mad Catz R.A.T. 2+. The Razer is a bit lighter and feels much sturdier. It has a more flexible cable and mouse feet that glide more smoothly. Also, it has a pair of side buttons on the left, which the Mad Catz lacks. Performance-wise, it has a wider CPI range and a much lower click latency. The Razer is best-suited for a fingertip grip for all hand sizes and small hands for other grip types, while the Mad Catz is only suitable for small and medium hand sizes using any grip type.
