Our Verdict
Razer Viper Mini
Finalmouse Starlight-12 Poseidon Small
The Razer Viper Mini and the Finalmouse Starlight-12 Poseidon Small are both lightweight gaming mice. The Razer is wired-only, and it has companion software for you to make adjustments to the sensor. On the other hand, the Finalmouse is about 20g lighter, which is impressive as it's a wireless mouse.
