Our Verdict

Razer Viper Mini Signature Edition

Finalmouse UltralightX

The Razer Viper Mini Signature Edition and the Finalmouse UltralightX are lightweight wireless gaming mice with similar symmetrical shapes and body designs with weight-saving cutouts. The Razer has marginally better overall sensor performance. It's also somewhat heavier, and its body is made of magnesium alloy. Conversely, the Finalmouse model has marginally lower click latency performance, and its body is made of a carbon fiber composite, making it somewhat lighter.
