Our Verdict
Finalmouse UltralightX
Razer Viper V3 Pro
The Razer Viper V3 Pro and the Finalmouse UltralightX are lightweight, high-performance, wireless gaming mice. The Finalmouse is significantly lighter than the Razer thanks to its carbon-composite shell with honeycomb-shaped cutouts. However, the Razer has superior build quality and a more conventional design with a solid plastic shell. The two mice perform very similarly overall, but at the time of writing, the Razer supports a higher maximum polling rate of 8000Hz, whereas the Finalmouse's is only 4000Hz.
